List Of Accidents And Incidents Involving Military Aircraft Before 1925

This is a list of notable accidents and incidents involving military aircraft grouped by the year in which the accident or incident occurred. Not all of the aircraft were in operation at the time. For more exhaustive lists, see the Bureau of Aircraft Accidents Archives or the Aviation Safety Network or the Scramble on-line magazine accident database. Combat losses are not included except for a very few cases denoted by singular circumstances.

Aircraft terminology

Information on aircraft gives the type, and if available, the serial number of the operator in italics, the constructors number, also known as the manufacturer's serial number (c/n), exterior codes in apostrophes, nicknames (if any) in quotation marks, flight callsign in italics, and operating units.

1861

;21 July
:Gen. Irvin McDowell requests that a balloon be brought to the front at the Battle of First Manassas, Centreville, Virginia. Mary Hoehling tells of the sudden appearance of Pennsylvania aeronaut John Wise who demanded that Prof. Thaddeus S. C. Lowe stop his inflating of his balloon "Enterprise" and let him inflate his balloon instead. Wise had legal papers upholding his purported authority. Although Wise's arrival on the scene was tardy, he did inflate his balloon and proceeded toward the battlefield. On the way the balloon became caught in the brush and was permanently disabled. His balloon became lodged in trees, which eventually tore the fabric. This ended Wise's bid for the position, and Lowe was at last unencumbered from taking up the task as Chief Aeronaut of the U.S. Army. "Lowe helped avoid panic after the First Battle of Manassas by ascending to a height of 3 miles and reporting that no Confederate forces were advancing on Washington."

1895

;4 July
:A large German military balloon burst at the German Army's Balloon Department grounds. Five balloonists were injured.

1907

;28 May
:Lieuts. Theodore E. Martin-Leake, 28, and William T. M'Clintock Caulfield, 27, of the British Army ascend at 1630 hrs. from the military balloon factory at Cove, near Aldershot, in the balloon ''Thresher'', witnessed by King Edward VII and Prince Fushimi Hiroyasu. For unknown reasons they do not descend a few hours later as planned, and the balloon is sighted over Weymouth at 2030 hrs., drifting towards the sea.Correspondents, "Lost War Balloon", ''Poverty Bay Herald'', Gisborne, New Zealand, Saturday 20 July 1907, Volume XXXIV, Number 11120, Supplement. The crew drown when the balloon crashes in Lyme Bay. The trawler ''Skylark'' (Captain Johnson) discovers the partially submerged balloon ten miles off Exmouth on 29 May and after some difficulty brings it into Brixham where it is transferred to the custody of Customs officials. Caulfield's body recovered at Weymouth on 24 June. Leake's body never found.

;2 June
:Captain of the Military Engineers Arnaldo Ulivelli's balloon departs from Ponte Milvio but is hit by lightning while flying above a military parade in Rome. He suffers from broken bones and burns as his balloon falls from 500 metres, crashes on the Via Cassia, not far from the intersection with Via della Camilluccia, and dies four hours later in San Giacomo Hospital. A stone memorial has been erected at the crash site.

;22 June
:A military balloon falls and explodes in Debrecen, Austria-Hungary. Its crew of two French Army officers and one Austro-Hungarian Army officer, and ten peasant men on the ground are killed. With thirteen fatalities it was the worst air accident until the 1913 Helgoland Island Air Disaster.

;30 November
:The French Army's first airship, '' Patrie'', is torn loose from temporary moorings at Souhesmes during a storm. After briefly touching down in Ireland, it is last sighted near the Hebrides.

1908

;20 May
:Brazilian Armed Forces officer Lt. Juventino Fonseca died from injuries sustained when his balloon prematurely took off during military inspection due to a gust of wind. As his balloon was still tethered, it crashed into the ground over Manaus.

;17 September
: Wright Model A, piloted by Orville Wright, crashes at Fort Myer, Virginia, killing Lt. Thomas E. Selfridge. During the flight, which had begun soon after 5pm., a propeller broke and severed control wires. The trials continued the following year with a new smaller version of the Wright A which became the first military aircraft when purchased by the US Army. This aircraft served for two years and was retired on 4 May 1911. It is now on display at the Smithsonian Institution National Air and Space Museum, Washington, D.C., after having been accepted for exhibition on 20 October 1911. Selfridge Air Force Base, Michigan, was later named for the first U.S. military aircrash victim. Wright was hospitalized until 31 October 1908 and spent several more weeks on crutches.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 32.
;16 October
:Pilot Samuel Franklin Cody takes off from Farnborough Common, Great Britain, in his British Army Aeroplane No 1, a biplane powered by a Antoinette 8V engine. His flight covers 424 metres before ending in a crash-landing, which he survives.

1909

;16 May: A French military balloon collides with electric light wires and is destroyed by fire at Paris.

;3 September:The French army airship ''La République'' sets off from Chalais-Meudon for a flight to Lapalisse. After 62 miles (105 km), while over La Charité-sur-Loire, the motor overheats due to poor water circulation and has to be stopped immediately, requiring the crew to land in poor conditions at Policards, in the commune of Jussy-le-Chaudrier. Some local farm workers who are present catch the guide ropes but are unable to prevent the gondola from impaling itself on an apple tree, which damages the airship’s keel and gondola in several places. With this damage and given the loss of a quantity of gas, it is decided not to risk the ''République'' suffering the same fate as the ''Patrie'' (which was lost when a storm blew up while she was moored in the open due to mechanical problems), but to deflate the gas-bag immediately. The gondola and keel are sent on to Lapalisse for repairs and the envelope returned for repairs to Chalais-Meudon.
;22 September :Capt. Louis F. Ferber, (1862–1909), of the French Army, is killed when he drags a wing during a low-altitude turn in a Voisin biplane at a flying meet at Boulogne, France, overturning the machine.Jane, Fred T., "Jane's All The World's Aircraft 1913", Sampson, Low, Marston & Company, Ltd., London, 1913, Aerial Who's Who, page 3D.New York City, New York, "Taft Sends Condolences", ''New York Times'', 22 May 1909. "Capt. Ferber was pinned to the ground."

;25 September
:French Army airship ''La République'' crashes over Avrilly, Allier, killing its crew of four. It was caused by a broken propeller which sheared through the envelope causing rapid leakage. This crash marks the first military airship fatalities.

;31 October
:Lieut. Pietro Rovetti is killed when struck by an airship propeller during takeoff in Rome.

;5 November
:The United States Army Wright Military Flyer, serial ''1'', piloted by Lieutenant Frank P. Lahm with 2nd Lieutenant Frederick E. Humphreys as passenger crashes into the ground at College Park Airport, Maryland, while executing a sharp right turn. The aircraft had lost altitude due to engine misfiring and the aircrew had not taken account of their proximity to the ground when banking the aircraft to the right. Both officers were unhurt but the aircraft required repairs. The skids and the right wing had to be replaced.

1910

12 July

At the age of 32, Charles Rolls (of Rolls-Royce fame) was killed in an air crash at Hengistbury Airfield, Southbourne, Bournemouth when the tail of his Wright Flyer broke off during a flying display. He was the first Briton to be killed in an aeronautical accident with a powered aircraft, and the eleventh person internationally. His was also the first powered aviation fatality in the United Kingdom.

;20 August :Lt. Marquis Vivaldi (also quoted as Lt. Pasqua Vivaldi), of the Royal Italian Army, is killed at Magliano, near Rome, in a Farman biplane. "In descending he lost control." The 28 January 1911 issue of '' Flight'' states that the "Motor stopped and machine was smashed; he was killed instantly."

;3 October: The first recorded collision between aircraft occurs at the Milano Circuito Aereo Internazionale meet held in Milan, Italy, when René Thomas of France in an Antoinette monoplane collides with Captain Bertram Dickson of the British army, the first British serviceman to qualify as a pilot, in a Farman biplane by ramming him in the rear. Both pilots survive but Dickson is so badly injured he never flies again.

;3 December
:The first multiple fatality airplane accident in history happened at Centocelle, near Rome, when Lt. Enrico Cammarota and Private S. Castellani became the 26th and 27th people to die in an aircraft crash.Henry Villard, ''Contact! The Story of the Early Aviators'' (Courier Dover Publications, 2002) p241; "The Fatalities of Flight", by Victor Lougheed, ''Popular Mechanics'' (August 1911) p173 Their Farman biplane broke during a turn and they died in a military hospital.
;30 December :French aviator Lt. Jacques de Caumont, 28, is killed in the 50 hp prototype Nieuport III monoplane, at St. Cyr, this date, when he suffers loss of control.

1911

;10 May
:First U.S. Army pilot casualty, 2nd Lt. George Edward Maurice Kelly (1878–1911), London-born, and a naturalized United States citizen in 1902, is killed when he banks his Curtiss Type IV (or Curtiss Model D), Army Signal Corps serial number ''2'', sharply to avoid plowing into an infantry encampment near the present site of Fort Sam Houston, Texas. The Aviation Camp (aka Remount Station) at Fort Sam Houston is renamed Camp Kelly, 11 June 1917, then Kelly Field on 30 July 1917, and finally Kelly AFB on 29 January 1948.Mueller, Robert, "Air Force Bases Volume 1: Active Air Force Bases Within the United States of America on 17 September 1982", United States Air Force Historical Research Center, Office of Air Force History, Washington, D.C., 1989, , page 267. Airframe rebuilt, finally grounded in February 1914, refurbished, and placed on display in the Smithsonian Institution National Air and Space Museum, Washington, D.C. Due to this crash, the commanding officer of Fort Sam Houston bans further training flights at the base, the flying facilities being moved to College Park Airport, College Park, Maryland in June–July 1911.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 49. A replica of this airframe is preserved at the National Museum of the United States Air Force.

;18 August
:The Royal Aircraft Factory S.E.1 crashes at Farnborough, pilot Lt. Theodore J. Ridge killed. Despite being Assistant Superintendent at the Factory, Ridge was an inexperienced pilot who had only been awarded his pilot's certificate the day before, and was described as "an absolutely indifferent flyer". The combination of an unskilled pilot and a marginally controllable aircraft proved fatal: the S.E.1 stalled in a turn and spun in, killing Ridge.

;17 September
:Lieutenant Reginald Archibald Cammell of the British Air Battalion was killed at Hendon while conducting a trial flight of an ASL Valkyrie Type B with his own engine fitted. The accident was not considered to be due to faults in the aircraft, but to have been caused by Cammell's lack of experience with the aircraft.

;24 September : His Majesty's Airship No. 1, intended as a scout for the Royal Navy, known as the "Mayfly", but designated ‘HMA ''Hermione''’ in public records because the naval contingent at Barrow were attached to HMS ''Hermione'', a cruiser moored locally preparing to act as its tender, breaks in two in high winds as it is being removed from its shed at Cavendish Dock for full trials. The design is never flown.

;18 November
:First British seaplane to leave the water, and the first seaplane to take off from British waters, an Avro Type D, the first of six of the type, piloted by Royal Navy Commander Oliver Schwann, lifts off from Cavendish Dock, Barrow-in-Furness, England, briefly, falls back into the water and is damaged.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 53. His lack of training betrayed him, and the first take-off was not followed by the first successful landing. The Avro will be repaired.

1912

;24 May:Ten days after successfully demonstrating the third Jacob Goedecker-built Fokker Spin for an Imperial German Army delegation, Anthony Fokker crashes at the Johannisthal aerodrome, near Berlin, Germany, falling about 40 feetEditors, "American Air Death Rate Is The Highest", ''Popular Mechanics Magazine'', Chicago, Illinois, July 1912, Volume 18, Number 1, page 169. when a wing bracing-wire breaks. Fokker is not hurt but his passenger Lt. von Schlichting is killed. Due to this accident, the hard wire bracing of the design is changed to a stranded cable. The Fokker M.1 through M.4 are developed for the German army from the Spin ("Spider").

;1 June: Herr Buchstaetler and Lt. Stille of the German aviation corps are killed in a crash at Berlin, Germany, this date.

;11 June
:Lieutenant Leighton W. Hazelhurst Jr. (July 1887 – 11 June 1912) and Arthur L. Welsh (14 August 1881 – 11 June 1912) are killed in crash of Wright Model C, U.S. Army Signal Corps serial number ''4'', in College Park, Maryland. Hazelhurst was the third U.S. army officer to die in an aeroplane crash. Airframe had recently been purchased by the Aeronautical Division, U.S. Signal Corps. The United States Army Signal Corps had established a series of tests for the aircraft, and Welsh and Hazelhurst were taking the Model C on a climbing test, one of the last in the series required by the Army. Shortly after takeoff, the aircraft pitched over while making a turn and fell to the ground, killing both crew members. They had both been ejected from their seats, with Welsh suffering a crushed skull and Hazelhurst a broken neck. ''The New York Times'' described Welsh as "one of the most daring professional aviators in America" and his flying partner Hazelhurst as being among the "most promising of the younger aviators of the army". A board of officers was formed by the United States Secretary of War Henry Lewis Stimson, which concluded that Welsh was at fault in the crash, having risen to 150 feet, with the plan to dive at a 45-degree angle in order to gain momentum for a climb, but had made the dive too soon, with the board's results reported in 29 June 1912 issue of ''Scientific American''. In a 2003 interview, a cousin of Welsh's reported the family's belief that the tests were run too rapidly and that Welsh was doomed to fail by carrying too much fuel and a passenger, giving a craft that would be unable to make the planned maneuver with the weight it was carrying.Thum, Robert
"The first Jewish aviator"
''The Dayton Jewish Observer'', 2003. Retrieved 5 August 2009. Hazelhurst Field, at Mineola, New York, a major World War I training facility, is named for the aviator.Editors, "How Aviation Fields Were Named", ''Air Service Journal'', Gardner, Moffat Co., Inc., New York, New York, 25 October 1917, Volume I, Number 16, page 503.

;19 June
:Capt. Marcel Dubois and Lt. Albert Peignan of the French Army are killed near Douai when their planes collide in mid-air, the first fatal mid-air collision in history. Unable to see each other in early morning haze, while making circuits over the airfield, their two biplanes impacted and the wire stays and canvas wings became interlocked, the two planes coming down together. Peignan dies on striking the ground and Dubois expires within the hour.

;26 June
:2nd Lt. Henry H. Arnold, holder of Fédération Aéronautique Internationale (FAI) pilot certificate No. 29 and Military Aviator Certificate No. 2, after accepting the Army's first tractor airplane, Burgess Model H, Signal Corps ''9'', crashes into Plymouth Bay, Massachusetts after takeoff, receiving the scar on his chin that he shows distinctively for the rest of his life.

;5 July
:Royal Flying Corps (RFC) Captain Eustace Loraine and his observer Staff Sergeant Richard H V Wilson were flying a Nieuport monoplane out of Larkhill, Wiltshire, England on a routine training flight. They were executing a tight turn when the aircraft fell towards the ground and crashed. Wilson was killed outright and although Loraine was speedily transported to Bulford Hospital in a horse-drawn ambulance, he died of his injuries only a few minutes after arriving at the hospital. Loraine and Wilson were the first Flying Corps personnel to die in an aircraft crash while on duty. Later in the day an order was issued which stated "Flying will continue this evening as usual", thus beginning a British military aviation tradition.

;31 July
:An attempt by the U.S. Navy to catapult launch the Navy's first seaplane, a Curtiss A-3 (AH-3) pusher, at the Washington Navy Yard, Washington, D.C., fails when a crosswind catches the aircraft halfway along the catapult and tosses it into the Anacostia River. Pilot uninjured.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 58. A different source lists the location of the launch attempt as Annapolis, Maryland, the aircraft as the Curtiss A-1 (AH-1), and the pilot as Lt. Theodore G. Ellyson, noting that the catapult was powered by compressed air, was fabricated by the Naval Gun Factory at the Washington Navy Yard from a design by Capt. Washington I. Chambers, and that the aircraft, not being secured to the catapult, reared up at mid-stroke where it was caught by the crosswind. This account, from an official U.S. Navy history, may be the more credible of the two versions. An accompanying photo (No. 650864) dated July 1912 showing the ''A-1'' on the catapult at Annapolis supports the latter description. The first successful launch was accomplished on 12 November 1912 at the Washington Navy Yard by Ellyson in the ''A-3'', according to this source, possibly accounting for the confusion.

;13 August
:During air-ground maneuvers held by the U.S. Army, at Stratford, Connecticut, Pvt. Beckwith Havens of the 1st Company, Signal Corps, New York National Guard, suffers engine failure in a Curtiss biplane at about 1000 ft (300 m) over a crowded parade ground, narrowly misses spectators and a cavalry troop as he swoops down, glides down the field and collides with a Burgess-Wright biplane that had just been flown by Lt. Benjamin Foulois, breaking off its tail. No injuries reported, and both aircraft are taken to hangars for repair. Havens, a pilot employed by pioneer aircraft builder Glenn H. Curtiss, had enlisted in the New York National Guard as a private in June 1912. At the National Guard manoeuvers with the Army, he flew an aircraft that his employer had loaned him.

;6 September
:Capt. Patrick Hamilton and Lt. Wyness-Stuart of the Royal Flying Corps are killed when their Deperdussin monoplane breaks up in flight, crashing at Graveley, near Welwyn. The Anzani-powered aircraft had been taken on strength by the army in January 1912.

;10 September
: Lts. E. Hotchkiss and C. A. Bettington are killed when their Bristol-Coanda monoplane suffers a structural failure and crashes. This second accident involving a Royal Flying Corps monoplane in five days causes Col. Seely, Secretary of State for War, to issue a ban on monoplanes on 14 September. The ban will be reversed five months later when technical studies show that monoplanes are no more dangerous than biplanes.

;28 September
:Wright Model B, U.S. Army Signal Corps serial number ''4'', crashes at College Park Airport, Maryland, killing two crew, Lieutenant L. C. Rockwell and Corporal Frank S. Scott. On 20 July 1917, the Signal Corps Aviation School is named Rockwell Field in honor of 2nd Lt. Lewis C. Rockwell, killed in this crash, and Scott Field, Illinois is named for the first enlisted personnel killed in an aviation crash. Scott Air Force Base remains the only U.S. Air Force base named for an enlisted man.

1913

;February
: Vickers E.F.B. 1 Destroyer (Experimental Fighting Biplane), the first of the Gunbus series of designs, contracted for in early 1913 by the Admiralty shortly after creation of the Naval Wing of the Royal Flying Corps in 1912, a pusher design, completed and displayed at the 1913 Olympia Aero Show, crashes soon afterwards, possibly on its first flight. No production ordered.Mason, Francis K., "The British Fighter since 1912", Naval Institute Press, Annapolis, Maryland, 1992, Library of Congress card number 92-63026, , pages 15–16.

;8 February
:Russian pilot N. de Sackoff becomes the first pilot shot down in combat when his biplane, possibly a Maurice Farman MF.7, is hit by ground fire following bomb run on the walls of Fort Bizani during the First Balkan War. Flying for the Royal Greek Army, he comes down near small town of Preveza, on the coast N of the Aegean island of Lefkada, secures local Greek assistance, repairs aircraft and resumes flight back to base.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 61.

;March
:Royal Aircraft Factory B.S.1 (c.f. Blériot Scout, indicating a tractor aeroplane), the first aircraft in the world designed and built from the start as a single-engine, single-seat fighting scout, first flown in March 1913 by Geoffrey de Havilland, crashes later that same month from a flat spin, pilot suffering a broken jaw. Repaired and modified, but no production ordered.Mason, Francis K., "The British Fighter since 1912", Naval Institute Press, Annapolis, Maryland, 1992, Library of Congress card number 92-63026, , page 14. Rebuilt as the B.S.2, then redesignated S.E.2 (Scout Experimental), and with enlarged vertical tail surfaces as the S.E.2A, and given serial ''609'', but still no production ordered.Mason, Francis K., "The British Fighter since 1912", Naval Institute Press, Annapolis, Maryland, 1992, Library of Congress card number 92-63026, , pages 21–22.

;8 April
:Lieutenants Rex Chandler and Lewis H. Brereton on training flight from North Island, San Diego, California, in Curtiss Model F flying boat, Signal Corps ''15'', with Brereton as pilot, crashes and Chandler is knocked unconscious and drowns. This was Chandler's first, and only, flight.Peck, Wallace R., "Forgotten Air Pioneers: The Army's Rockwell Field at North Island", ''The Journal of San Diego History'', Fall 2006, Volume 52, Numbers 3-4, page 107. Chandler, of the Coast Artillery Corps, had reported for aeronautical duty at the Signal Corps Aviation School on 15 March 1913. Chandler Field at Essington, Pennsylvania, opened in 1917, is named for the late pilot.

;17 April :The French military balloon Zodiac collapses in flight over Noisy-le-Grand, France, killing five.Langland, James, M. A., compiler, "Almanac and Year-Book for 1914", The Chicago Daily News Company, Chicago, Illinois, 1913, page 396.

;9 May: "By Associated Press to THE SUN KOENIGSBURG, Germany, May 9. - A German military spherical balloon, the "Cassiopeia," which ascended from this city on Wednesday, is missing with its passengers. It was last seen in the neighborhood of Pillau, about 35 miles from here, traversing the Frischen Ehrung 'sic''peninsula in a storm." "It was under the command of Captain Von Wobeser of the second balloon battalion, stationed here."

;9 May: "By Associated Press to THE SUN LOS ANGELES, May 9. - Within 40 miles of his goal Lieutenant Joseph D. Park, the army aviator, flying from San Diego to Los Angeles, met death at Olive, nine miles north of Santa Ana, this morning. He had lost his way in a mist a short time before and had landed. He soon recovered his bearings, and attempted to reascend, but the machine plunged against a tree and turned over, the engine crushing the head of the aviator. Little girls on their way to school were among the horrified spectators of the tragedy. Park was recently transferred from the fourteenth cavalry to the army aviation corps at San Diego." Park (1882–1913) was assigned to the 1st Aero Squadron. Park Field at Memphis, Tennessee, is named for him.

;27 May
:Lieutenant Desmond Arthur died when his Royal Aircraft Factory B.E.2 biplane, ''205'', collapsed without warning while flying over Montrose. This was Scotland's first fatal aircraft accident.

;20 June:First fatality in U.S. Naval aviation occurs when flight instructor Ens. W.D. Billingsley, flying from the aviation encampment at Greenbury Point, Maryland, is thrown from pilot seat of the second Wright CH seaplane, ''B-2'', at height of 1,600 feet in turbulent air over Annapolis, Maryland. Passenger Lt. John Henry Towers stays with airplane, sustaining injuries when it hits water. Design was modified conversion of Wright Model B with two pusher propellers driven through chains connected to a Wright engine.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 62. Billingsley was Naval Aviator Number 9.

;23 June
:The ''S-21 Sikorsky Russky Vityaz'' ("Russian Knight"), designed by Igor Sikorsky and built by the RBVZ, a redesigned variant of the Bolshoi Baltiski, as the first large aircraft intended exclusively as a bomber, first flies on this date, the world's first four-motored aircraft. It is lost in a freak accident during 1913 military trials when the Gnôme rotary on a Moller II pusher biplane (some sources cite a Morane design) tears loose and hits the giant bomber.

;17 July
:Major Alexander William Hewetson of the 66th Battery Royal Field Artillery was killed flying near Stonehenge in Wiltshire. A stone memorial was erected near the spot. This can be seen by the road between the Stonehenge visitors' centre and the monument by the Fargo Wood.

;4 September
:U.S. Army 11th Cavalry 1st Lt. Moss Lee Love becomes the 10th fatality in U.S. army aviation history when his Wright Model C biplane crashes near San Diego, California during practice for his Military Aviator Test. On 19 October 1917, the newly-opened Dallas Love Field in Dallas, Texas is named in his honor. Joe Baugher lists the fatal aircraft accident for this date as being Burgess Model J, Signal Corps ''18'', which dove into the ground killing its pilot.

;9 September
:Imperial German Navy Zeppelin, ''L 1'', LZ14, pushed down into the North Sea off Helgoland in a thunderstorm, drowning 14 crew members. This was the first Zeppelin incident in which fatalities occurred. Seven crew rescued by motor torpedo boats.

;13 October
: Imperial German Air Force-Lt. Koening killed in crash near Neuendorf Aerodrome near Berlin. Lts Soren and Rohstadt are injured while taking a flight between Berlin and Stuttgart

;17 October
: Imperial German Navy Zeppelin ''L 2'', LZ18, destroyed by an exploding engine during a test flight – the entire crew of 28 was killed.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 63.

;14 November :Wright Model C, Signal Corps ''12'', stalls and crashes into Manila Bay, the Philippines, killing the pilot. One source identifies him as Loren Call, while another gives his name as Lt. Perry Rich. The ''Almanac and Year-Book for 1914'' gives his name as Lt. C. Perry Rich.

;24 November
: Lieuts. Eric Lamar Ellington, chief instructor, and Hugh M. Kelly of the 1st Aero Squadron, United States Army Aviation Corps, are killed this date in a fall of about eighty feet in a Wright Model C, Signal Corps ''14''. The accident occurred at ~0758 hrs. across the bay from San Diego, California on the grounds of the army school on North Island. On impact, the engine broke free, crushing the two aviators. These were the eleventh and twelfth Army aviation casualties. "The front page of the ''San Diego Union'' was devoted to the details of the Ellington/Kelly crash, under the headline 'Intrepid Navigators of Air Crushed, Mangled to Death in Fall of Government Biplane,' with charges that the aviators were 'slaughtered' by a parsimonious government using antiquated machines." Ellington Field, Texas, which opens on 1 November 1917, is named for Lt. Ellington.

;7 December
:A Royal Aircraft Factory B.E.2a, ''235'', flown by factory test pilot Lt. Norman Spratt crashed at the Farnborough Aerodrome, pilot surviving.Cooper, Peter J., "Picking up the Pieces", ''Air International'', Stamford, Lincs., UK, November 1998, Volume 55, Number 5, page 280.

1914

;9 February
:U.S. Army Lt. Henry Post exceeds his previous altitude records by reaching 12,140 feet. During descent, the Wright Model C, Signal Corps ''10'', aircraft sustained damage (wing collapsed) and crashed into San Diego Bay, killing Lt. Post. On 24 February, due to a large number of accidents and deaths, an Army board at the Signal Corps, Aviation School, San Diego, condemned all pusher airplanes. This recommendation basically condemned all Wright aircraft, which were all pushers. Post Field is established at Fort Sill, Oklahoma, named for the aeronaut.

;16 February :Lieutenant (jg) James M. Murray, Naval Aviator No. 10, on a flight at Pensacola, Florida, in the Burgess D-1 flying boat, crashes to the water from 200 feet and is drowned. This was the first flying fatality at Pensacola and it came only two weeks after flight operations began there. Flights were suspended for two days out of respect for the lost aviator. Of the first ten Naval aviators, half would die in crashes.

;9 March:Lieutenant Alejandro Bello Silva was a Chilean aviator who disappeared during his qualifying flight for certification as a military pilot. In the pre-dawn hours, this date, Lieutenant Silva was in the Lo Espejo aerodrome, where he was to take an examination to earn the designation Military Pilot. Bello and two companions had to complete the circuit from Lo Espejo to Culitrín, to Cartagena, and back to Lo Espejo, in the central region of Chile, in order to pass the exam. On the first attempt, the aviators had to return to base due to near-zero visibility caused by heavy fog. Bello damaged his aircraft during the landing, and switched to an Sánchez-Besa biplane (tail number ''13'', nicknamed "Manuel Rodríguez") for the second attempt. He took off together with one companion and the instructor, who had to make an emergency landing for refueling. Nevertheless, Bello continued his route and was lost among the clouds. He was never seen again and many searches over time have failed to find any trace of him or his aircraft.

;12 May or 25 May
:First fatal mid-air between two machines of the Royal Flying Corps kills Capt. Ernest Vincent Anderson and his passenger Air Mechanic Henry Wifred Carter when their Sopwith Tractor Biplane, ''324'', was accidentally rammed by Lt. C. W. Wilson in another Sopwith, ''325'', of the same type. Wilson was returning from Brooklands and descending to land at Farnborough when he struck the other plane, which was climbing away from the aerodrome on a familiarization flight. Wilson escapes with bruises and a broken jaw. Both planes crash on the nearby Aldershot Golf Course 10th Green. Both machines and all three airmen were from No. 5 Squadron, RFC.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 67.

:First fatal British seaplane accident kills Lt. T. S. Cresswell and Cmdr. A. Rice of the Royal Navy. While ascending from the Calshot Air Station, the Short S.128 they are flying passes over motorboat on Southampton Water where Short's test pilot Gordon Bell and Lt. Spencer Grey are watching flight. At height of just over 200 feet, seaplane appears to break up and plummets into sea, killing both occupants. Some witnesses say that they believed that the seaplane stalled and that the wings folded up as structural limits were exceeded.

;20 June
:While the Austro-Hungarian airship '' Militärluftschiff III'' (or ''M.III'') hovers over Fischamend testing new camera equipment, an Austro-Hungarian Army pilot tries to loop ''M.III'' in a Farman biplane. The airplane strikes the top of the airship, tearing a hole and igniting the escaping hydrogen gas. Both aircraft are destroyed, and both men in the airplane and all seven men aboard ''M.III'' are killed. It is the end of the Austro-Hungarian airship program.

;26 June
:The prototype Bristol S.S.A. (for Single-Seat Armoured), c.n. 219, a Henri Coanda single-seat tractor biplane design intended for production France, crashes on landing at Filton when an undercarriage bracing wire fails. Pilot Harry Busteed slightly injured, but airframe is severely damaged. The French authorities however agree to accept delivery of the type at the Breguet factory, where it is rebuilt, and Bristol takes no further part in its development.

;27 June
:During a training exercise close to the Belgium-Luxembourg border, Lt. Felix Liedel became the first Belgian Armed Forces aviation casualty. While piloting a Jero-Farman biplane, one of the tension cables became entangled in the propeller, resulting in his crash near Martelange. Liedel was mortally wounded, and died in a military hospital just after midnight the following day.

;9 July
:During an attempted take-off from Kiewit Airfield, Belgian Army lieutenants Raymond Hubert and Lucien Poot were involved in an air crash. When the wheels of their Jero-Farman biplane left the ground, the aircraft sharply turned to the right and crashed into a hangar at high speed. While Poot escaped with minor injuries, Hubert was mortally wounded, dying the following day.

;26 July
:Seventh aircraft erected at Tokorozawa Airfield, Japan, the Kaishiki Converted Type Mo (Maurice Farman Type), ''7'', crashed at this airfield while piloted by Capt. Yoshitoshi Tokugawa. When rebuilt, with completion on 19 January 1915, this 7th Type Mo 1913 became known as the Sawada Type No. 7, or more officially because of radical modifications, as the Kaishiki the 3rd Year Model.Mikesh, Robert C., and Abe, Shorzoe, "Japanese Aircraft 1910–1941", Naval Institute Press, Annapolis, Maryland, 1990, , pages 49–50.

;12 August
:Sole Royal Aircraft Factory S.E.4, ''628'', crashlands at 1145 hrs. while being flown by Lt. Norman Spratt when one of the wheels collapsed, airframe overturning, sustaining such extensive damage that it is abandoned.

;8 September
:Imperial Russian Army pilot Pyotr Nesterov attempted an aerial ramming against an Austro-Hungarian reconnaissance Albatros B.II with his Morane-Saulnier. He most likely tried to hit it with his landing gear but accidentally used his propeller instead. As a result, both planes crashed killing Nesterov and the two in the opposing aircraft over Zhovkva, Ukraine.

;5 October
:First aerial combat kill in history recorded when a Voisin III pusher of Escadrille VB24, French Air Service, flown by Sgt. Joseph Frantz and Cpl. Louis Quénault, downed a German two-seater Aviatik B.II, ''114/14'', of FFA 18, flown by ''Feldwebel'' Willhelm Schlichting with ''Oberleutnant'' Fritz von Zangen as observer,Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 72. over Jonchery, Reims, using what is believed to have been a Hotchkiss machine gun.

:Lt.j.g. Richard Caswell Saufley of the U.S. Navy, designated Naval Aviator No. 14, is killed in the crash of a Curtiss Model E hydro-plane (seaplane), ''AH-8'', over Santa Rosa Island near Pensacola, Florida at the 8 hr., 51 min. mark of an attempted long-duration flight. Saufley Field, north of NAS Pensacola, is subsequently named for him.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 84.

;18 June
:German ace Max Immelmann (17 victories) is killed at ~2215 hrs. when his Fokker E.III monoplane, ''246-16'', crashes after breaking up in the air when the interrupter gear malfunctions and he shoots away his own propeller. He had been engaging an F.E.2b piloted by 2nd Lt. G. R. Gubbin with Cpl. J. H. Waller as gunner.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 86. Gubbin and Waller were credited with the victory, but another theory posits that Immelmann may have taken hits from friendly AAA, as the propeller failure would not necessarily have caused the complete airframe disintegration that occurred.

;Afternoon of 27 June
:Fokker's chief designer and test pilot Martin Kreutzer takes a Fokker D.I for a test flight, but when he kicks the rudder hard over, it jams and he is severely injured in the subsequent crash, dying in hospital the next day.

;26 September
:Flying ace ''Leutnant'' Max Ritter von Mulzer (ten aerial victories credited), the first Bavarian fighter ace, first Bavarian ace recipient of the Pour le Merite, and first Bavarian knighted for his exploits, on this date sideslips Albatros D.I ''426/16'' into a hard bank, loses control, and crashes at Armee Flug Park 6, Valenciennes, with fatal result.

;28 October
:Undercarriage of German fighter pilot Erwin Böhme, diving on a British fighter, strikes upper wing of ace Oswald Boelcke's Albatros D.II, also pursuing the same target. Fabric peels loose, aircraft disappears into cloud – when it emerges, the top wing is gone. Boelcke makes relatively "soft" landing, but as he habitually flew without a helmet, and in haste to take off had not properly secured his seatbelt, he was killed on impact. He was 25, and was credited with 40 victories. Jasta 2 is officially named "Jasta Boelcke" on 17 December 1916 in honour of its former commander.

;7 November
:Imperial German Army Zeppelin ''LZ90'', LZ60, broke loose in the direction of the North Sea in a storm and never seen again.

;13 November
:Sole prototype of the Zeppelin-Lindau (Dornier) V1, a single-seat, all-metal fighter with pod-type fuselage and pusher Maybach Mb III engine, designed by Dipl-Ing Claudius Dornier, and built by the Abteilung 'Dornier' of the Luftschiffbau Zeppelin GmbH at Seemoos, near Friedrichshafen, attempts initial flight. After a series of ground hops in September by Bruno E. Schröter, this pilot refused to fly the prototype due to pronounced tail-heaviness. Oblt. Haller von Hallerstein, instead undertakes initial flight this date, but the V1 performs a loop immediately after take-off, crashing, killing pilot. No further development undertaken of the type.

;12 December
:Sole prototype of Kishi No.2 ''Tsurugi-go'' ("Sword" type) Aeroplane, 'II', single-engine pusher biplane, makes first and last flight when Lt. Inoue lifts off, immediately banks sharply to port, wingtip contacts ground, airframe cartwheels sustaining considerable damage. Cause of accident assumed to be due to the sweptback wing design.Mikesh, Robert C., and Abe, Shorzoe, "Japanese Aircraft 1910–1941", Naval Institute Press, Annapolis, Maryland, 1990, , page 80.

;28 December
:Imperial German Navy Zeppelin LZ69 ''L 24'', crashed into a wall while being "stabled", broke its back, and burned out together with ''L 17'', LZ53.

;1 January
:Five Royal Naval Air Service crew en route from Manston, England to Villacoublay, France in a Handley Page 0/100 bomber, run into clouds, lose their direction due to a compass fault, and land to ask directions. Unfortunately, they come down behind German lines at Chalandry, near Lâon, France, and before they can either burn the machine or take off, a German infantry patrol captures them and their intact bomber. An unconfirmed story states that Manfred von Richthofen flew this machine to 10,000 feet before the Kaiser at a later date.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 92. Another source cites 2 February as the date of this incident.
;21 January
:Sergente Menegoni of 71 Squadriglia, ''Regio Esercito'', was killed when his Nieuport 11, ''1622'', suffered a structural failure of the wing struts and crashed.

;28 January
: Royal Aircraft Factory test pilot Maj. Frank W. Goodden is killed in the second prototype S.E.5, ''A4562'' at RAE Farnborough, when it breaks up in flight. At the time of his death, Goodden was one of Britain's most experienced pilots. Inspection found that the wings had suffered failure in downward torsion. Plywood webs were added to the compression ribs, curing the trouble and were standardized on all later S.E.5s and 5a's.London, UK: Aeroplane, Maynard, John, "''Think of the Risks...''", March 2006, Volume 34, Number 3, No. 395, page 31.

;12 March :Flight Sub-Lieutenant Ronald Victor Knight, Royal Naval Air Service, died at RAF Cranwell on 12 March 1917 where he was an assistant flying instructor. The engine of the plane in which he was flying failed and he dived to his death. He is buried in Wells Cemetery, Somerset and his name is shown on the war memorial in Wells.
;26 March
:Ex-Royal Flying Corps pilot J. B. Fitzsimmons is killed while engaging in some low level aerobatics in a high wind in the sole Nestler Scout (no serial) when the fabric began stripping from the wings. Fitzsimmons crashes into a hangar and the airframe is wrecked. No further development work takes place on the design.

;June
:During this month, six Russian Anatra D biplanes crash due to poor quality manufacturing, killing their pilots. The Russian aircraft builder was hampered by a shortage of high-quality wood and fabricated each wing spar in two pieces, overlapping at the joint by only 12 inches, held together with glue and tape.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 97.

;16 June
:Imperial German Navy Zeppelin ''L 40'', LZ88, damaged beyond repair in a failed landing at Nordholz Airbase.

;July
:Even though Vickers already had experience in building promising tractor scouts, and the pusher-style Gunbus had been outmoded for two years in the presence of dedicated dogfighters, the company built one prototype Vickers F.B.25, powered by a 150-hp. direct-drive Hispano-Suiza engine in 1917, armed with one 1.59 inch Breech-Loading Vickers Q.F. Gun, Mk II (popularly known as the "Vickers Crayford rocket gun") in the nose as an anti-airship night fighter. A ten-inch searchlight was intended to be fitted in the extreme nose but there is no evidence that this was ever installed. Design underwent trials at Martlesham Heath in late June or early July, but crashed whilst landing in a strong wind, a trials report stating that due to poor controls, the aircraft proved to be "almost unmanageable in a wind over 20 mph". The serial of this aircraft is not known, although a document, traced recently, refers to it as No. "13", and it has been suggested that this may indicate ''A9813'' – formerly a cancelled number intended for a Sopwith Triplane.

;21 July: French test pilot/instructor Jean Robinet, awarded Aviator's Certificate No. 476 by the Aéro-Club de France on 29 April 1911, is KWF an Anatra D at the Anatra Factory, Odessa, Russia, this date.

I., was killed when the military biplane under his control fell from a height of 800 feet, Aug. 2. Sergt. Thomas F. Pell, a student aviator with Captain Taylor, was injured." The Aviation Archeology database has no listing for this accident.

;3 August :"When the motor of his airplane stopped 300 feet up and the machine fell during his first flight, C. B. Lambert of Welch, W. Va., a student at the West Virginia Aviation School at Beech Bottom, was killed August 3. E. L. Frey, a member of the British Royal Flying Corps, an instructor at the school, was accompanying Lambert and sustained serious injuries." The Aviation Archeology database has no listing for this accident.

;7 August
:Squadron Commander Edwin H. Dunning, RNAS, (17 July 1892 – 7 August 1917) during landing attempt aboard , Pennant number 47, in Sopwith Pup, ''N6452'', decides to go around before touchdown, but Le Rhône rotary engine chokes, Pup stalls and falls into the water off the starboard bow. Pilot stunned, drowns in the 20 minutes before rescuers reach still-floating airframe. Dunning had made two previous successful landings on ''Furious'', the first-ever aboard a moving vessel.Bruce, J.M., "Sopwith's Pedigree Pup", ''Air Enthusiast'' Quarterly, Bromley, Kent., UK, Volume 4, 1976, pages 204.

;17 September
:A kite balloon from the was hit by a squall and while being hauled down struck the water so hard that the observer, Lieutenant (jg) Henry W. Hoyt, was knocked out of the basket and caught underwater in the balloon rigging. As the balloon was pulled toward the ship, Patrick McGunigal, Ships Fitter First Class, (30 May 1876 – 19 January 1936) jumped overboard, cleared the tangle and put a line around Lieutenant Hoyt so that he could be hauled up on deck. For this act of heroism, McGunigal was later awarded the Medal of Honor, the first of the Great War. The ''Huntington'' was convoying six troopships across the Atlantic to France and the balloon observation was being made as it transited the war zone.

:Imperial German Navy Zeppelin LZ50 ''L 16'', damaged beyond repair in a forced landing near Brunsbüttel.

;29 October
:Lt. Heinrich Gontermann, known as the Balloon Strafer, receives fatal injuries when the Fokker Dr.I ''115/17'', of '' Jasta 15'', he is performing aerobatics over his airfield at 1,500 feet in, suffers structural failure as the top wing breaks up, crashes, suffers grievous facial injuries, dies the following day. The Triplane had been delivered to ''Jasta'' 15 on 22 October but foul weather kept it grounded until the 28th. Gontermann had scored 21 airplane kills and 18 balloons.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 103.

;31 October
:Fokker Dr.I ''121/17'', flown by Lt. Pastor from '' Jasta 11'', one of the JG.1 units under Manfred von Richthofen, suffers structural failure and crashes. Second such crash in three days causes all Fokker Triplanes to be grounded immediately with affected flight crew reverting temporarily to Albatros D.Va and Pfalz D.III scouts. Accidents are investigated 2 November, reports issued 13 days later. Instructions for manufacturing and assembly improvements are implemented, production and flying resume 28 November.

;22 November
:A Tellier T.3 seaplane piloted by U.S. Navy Ensign Kenneth R. Smith, with Electrician's Mate Wilkinson and Machinist's Mate Brady on board, was forced down at sea on a flight out of NAS LeCroisic, France, to investigate the reported presence of German submarines south of Belle Isle. Two days later, and only minutes before their damaged aircraft sank, they were rescued by a French destroyer. It was the first armed patrol by a U.S. Naval Aviator in European waters. Smith was Naval Aviator No. 87.

;December
:Second prototype Sopwith Snipe, ''B9963'', tricky to fly as its Bentley BR2 rotary engine had immense torque that made directional control difficult, as well as being tail heavy while climbing, and nose heavy while diving, crashes, probably at RAE Farnborough, England. This airframe may have been a rebuild of B.R.1-engined prototype.

;1 December :A Caproni Ca.4 bomber, c/n 5349, which arrived at Langley Field, Virginia, as part of a shipment of various Italian aircraft in September 1917, but whose erection was delayed by lack of an appropriate hangar, is finally readied for flight on this date. Upon takeoff, one motor fails and unable to maintain airspeed on the remaining two powerplants, the airframe piles up on the edge of the field. No injuries, but the airframe is a total loss.

;12 December
: North Sea class blimp ''N.S.5'' sets off for RNAS East Fortune, but both engines fail within sight of her destination, and she drifts with the wind for about before they can be restarted. However, since both engines continue to be troublesome it is decided to make a "free balloon" landing, but the ship is damaged beyond repair during the attempt.

;Early 1918
:Sole prototype of the Curtiss CB (Curtiss Battleplane), unofficially known as the "Liberty Battler", ''34632'', an experimental two-seat fighter developed and flown early in this year as a result of difficulties being experienced with the Liberty-engined version of the Bristol F2B, proves to have extremely poor handling characteristics and subsequently crashes early in its test programme. Three additional airframes, ''34633-34635'', cancelled.

;5 January
:Imperial German Navy Zeppelin, ''L 47'', LZ87, destroyed by a giant explosion at the air base in Ahlhorn, along with ''L 46'', LZ94, ''L 51'', LZ97, and ''L 58'', LZ105, and one non-Zeppelin-type airship, stabled in three adjacent hangars. This is supposed to have been an accident, though sabotage could not be ruled out.

;7 February
:During U.S. Navy tests of a converted Curtiss N-9 biplane as an unpiloted flying bomb, equipped with a Sperry automatic control, Lawrence Sperry takes it up to prove airworthiness of the design, crashes, but pilot unhurt.Baker, David, "Flight and Flying: A Chronology", Facts On File, Inc., New York, 1994, Library of Congress card number 92-31491, , page 108.

Kynoch took off at 2329 hrs. while Stroud took off at 2330 hrs., both attempting to intercept a German raider headed for London, but collided on a moonless night, both coming down in Dollymans Farm. Stroud is buried in the churchyard of St. Andrews Church in Rochford. Kynoch is buried in St. Pancras and Islington Cemetery in north London.

;10 March
:Sole prototype Nieuport B.N.1, ''C3484'', operating out of Sutton's Farm, a home aerodrome, Great Britain, catches fire in the air and is destroyed. No further development undertaken.

;13 March: "NORFOLK, Va., March 14. - Falling while 300 feet in the air in a seaplane, Ensign Leslie M. Macnaughton, U. S. N. R. F., was drowned and Cadet Malcolm Stevenson was slightly injured." "The plane was completely wrecked. It had not been determined tonight what caused the accident. MacNaughton's body was recovered soon after the accident by a navy craft. Stevenson was clinging to the wreckage, slightly stunned, but otherwise uninjured." Leslie Malcolm MacNaughton, Reserve Force (class 5), born 2 October 1894, was an undergraduate at Yale University, where he joined the Yale Flying Squadron (third Yale Unit). He left school to become a pilot during the World War, being designated Naval Aviator Number 330 on 28 January 1918, and was flying from Naval Air Station Hampton Roads.

;14 March: " HUSTON, 'sic''March 14. - Lieut. Marmaduke Earle of Louisburg, 'sic''Pennsylvania, and Nile Gelwick of Findlay, Ohio, were killed at Ellington field 'sic''today and Civilian Instructor Kaiser was seriously injured internally in falls in airplanes resulting from a tail spin. Both accidents were attributed to high wind which prevented the young fliers gaining control of the planes when they fell into the tail spin." The Aviation Archeology database lists pilot Miles W. Gelwicks as killed in Curtiss JN-4D, ''SC-25056'', at Ellington Field this date, and M. M. Earle killed in an unknown airframe.

;14 March: "FORT WORTH, March 14. - Lieut C. Finch of the Royal flying corps 'sic''and Cadet Flier Howard P. Bittinger of the United States aviation corps were seriously injured here when the engine of their airplane stopped at an altitude of 500 feet and they fell at Camp Hicks." The Aviation Archeology database does not list this accident.

;15 March :"SAN DIEGO, Cal., March 15. - Flying Cadet M. J. Lazelli had a narrow escape from death about noon today while on flight duty near Rockwell field. 'sic''Lazelli, flying almost a mile high, was practicing trick evolutions and failed to come out of the drop known as the 'falling leaf.' The machine developed a tail spin and fell 4000 feet into the bay. Lazelli was rescued almost immediately after he struck the water, escaping with only slight bruises. The airplane was but slightly damaged."

;18 March :"FORT WORTH, March 18. - Cadet Flier Ellis B. Watts was instantly killed and Capt. L. V. Drake was injured when their airplane fell 300 feet in a spinning nose dive. Cadet Watts' home was in Portland, Oregon." The Aviation Archeology database shows L. V. Drake as pilot of an unidentified airframe in an accident at Camp Everman, Texas.

;18 March: "By Associated Press to THE SUN SAN DIEGO, March 18. - Flying Cadet Ralph T. Simpson, 27 years old, of Pasadena, was instantly killed this afternoon, when, emerging from a long nose dive in his airplane, he emerged from the dive upside down and fell to the water near North Island a distance of 100 feet. The machine landed on the cadet as he struck the water and was totally wrecked by the crash. Simpson's body was soon recovered and plans were made to send his body to Pasadena late tonight. Simpson was what is technically known as a second solo flier and had been making rapid progress in his training work. The accident was the first of the kind on record here. Simpson was the third cadet killed in practice work here, although Rockwell Field at North Island has turned out hundreds of young aviators in the last few months, their total length of flights being more than 50 times the circumferenece 'sic''of the globe." Another report described the fall as being 1,500 feet, although this may refer to the length of the dive. It continued that Simpson was alone in the plane, and that he had only been at the aviation school for one month, having come from the preliminary training school at the University of California. The Aviation Archeology database shows Simpson crashing into San Diego Bay in Curtiss JN-4, ''SC-953'', this date.

(''Eindekker V'', or monoplane five), six of which are delivered to ''Jasta 6'' of the Imperial German Air Service on 7 August, to occur in a week, kills ''Leutnant'' Emil Rolff when wing fails, and, like the Fokker Dr.I, Fokker Triplane before it, the type is grounded for investigation. Problem traced to shoddy workmanship at the Mecklenburg factory where defective wood spars, water damage to glued parts, and pins carelessly splintering the members instead of securing them are discovered. Upon return to service two months later, design is renamed the Fokker D.VIII in an effort to distance type's reputation as a killer. Rolff had scored the first kill in the type on 17 August.

:A U.S. Army seaplane en route on afternoon flight from Balboa, Panama to France Field, near present-day Colón, Panama, with three aviators on board, suffers engine failure shortly after departure. Pilot Lt. J. R. L. Hitt attempts landing on Miraflores Lake but aircraft falls short and hits the front of the Miraflores (Panama), Miraflores Locks of the Panama Canal at ~1700 hrs. Airframe crumples "like a house of cards", according to account published by the ''Panama Star & Herald'' on 3 May. Hitt, Lt. Thomas Cecil Tonkin, and Maj. Harold Melville Clark (4 October 1890 – 2 May 1919) are all thrown from the aircraft into the water of the lock. "Lieutenant Tonkin was undoubtedly killed instantly by the twisting timbers of the machine. ...Major Clark sank to the bottom of the lock, and it's not known whether he was killed in the crash or whether he drowned", stated the article. Hitt was severely injured in the crash, but was rescued by bystanders. The ''Panama Star & Herald'' reported that a diver was sent to retrieve Clark's body.

In the early hours of 15 July on what was officially supposed to be a mine-hunting patrol, she was seen to fly beneath a long "greasy black cloud" off Cley next the Sea on the Norfolk coast and a massive explosion was heard shortly after. A vivid glare lasted for a few minutes as the burning airship descended, and finally plunged into the sea after a second explosion. There were no survivors, and the findings of the official Court of Enquiry were inconclusive, but amongst other possibilities it was thought that a lightning strike may have caused the explosion.''Loss of N.S.11.''

:Top World War I Russian ace Aleksandr Kazakov (32 kills, but only 20 officially) is killed in the crash of what was probably a Sopwith Camel. On 1 August 1918 Kazakov became a major in the Royal Air Force and was appointed to be commanding officer in charge of an aviation squadron of the Slavo-British Allied Legion made up of Camels. After the British withdrawal from Russia which left the Russian White movement, White Army in a desperate situation, Kazakov died in an aircraft crash during an air show on this date which was performed to boost the morale of the Russian anti-Bolshevik troops. Most witnesses of the incident thought Kazakov committed suicide.

;10 August : Lts. Harold G. Peterson, pilot, and Paul H. Davis, observer-gunner, depart from Marfa Airport (original), Marfa Field, in the Big Bend (Texas), Big Bend area of Texas, on a routine Sunday morning patrol of the U.S.-Mexican border, in Curtiss JN-4D, ''24146'', based at Fort Bliss, El Paso, Texas, "Their mission was to patrol along the Rio Grande from Lajitas, Texas, Lajitas to Bosque Bonito and then land at Fort Bliss. Coming to the mouth of the Rio Conchos at Ojinaga, Chihuahua (opposite Presidio, Texas), they mistook the Conchos for the Rio Grande and followed it many miles into Mexico before being forced down by engine trouble. Thinking they were still on the Rio Grande, the airmen picked a spot on the "American" side of the river to land. The terrain was rough and the plane was wrecked. Having buried the machine-guns and ammunition to keep it out of the hands of bandits, Peterson and Davis started walking down the river, thinking they would come to the U.S. Cavalry outpost at Candelaria, Texas, Candelaria, Texas." It is assumed when they fail to arrive at Fort Bliss that they have either returned to Marfa, Texas, Marfa or had been forced down. A search is begun on 11 August as far south as Chihuahua City, but the flyers, caught in thick brush, are not seen when overflown on 12 August by a plane following the Conchos. Search continues until Sunday, 17 August, when word is received by Capt. Leonard F. ("Two-Gun") Matlack, commanding Troop K, 8th Cavalry Regiment, 8th Cavalry, at Candelaria, that the airmen are being held for ransom. "The flyers had been taken prisoner on Wednesday, August 13, by a Villista desperado named Jesus Renteria. The bandit sent the ransom note to a rancher at Candelaria, along with telegrams which he forced the airmen to write to their fathers and the Secretary of War, the Commanding General of the Southern Department, and the Commanding Officer of U.S. forces in the Big Bend District. Renteria demanded $15,000 not later than Monday, August 18, or the two Americans would be killed." The War Department authorizes the payment, and local ranchers subscribe to the full amount so that it can be disbursed from the Marfa National Bank. Negotiations through intermediaries see Captain Matlack crossing the border on Monday night to swap half the money for one American. All goes smoothly and in 45 minutes he returns with Lieutenant Peterson. But en route to the rendezvous with the other half of the ransom, Matlack overhears Renteria's men discussing killing both Americans once they have the money. At the meeting, Matlack pulls a gun, directs the Mexicans to tell Renteria to "go to hell", and, avoiding the ambush, rides back across the border with Lieutenant Davis. On Tuesday, 19 August, Capt. Matlack leads Troops C and K, 8th Cavalry, in pursuit of Renteria and his gang. Air Service planes scout ahead, and 1st Lts. Frank Estill and Russell H. Cooper spot three horsemen in a canyon ~12–15 miles W of Candelaria in late afternoon. When they close for a look, the riders fire on the DH.4. Estill makes a firing pass with his machine guns and Cooper opens up with his Lewis guns, killing one man, reportedly Renteria. The search for the gang continues until 23 August when, with the Mexican government protesting the invasion of its territory, American forces return to the U.S. The loss of JN-4D ''24146'' was recorded 13 August.

;21 August :Two U.S. Army officers of the 9th Bomb Squadron, 9th Corps Observation Squadron, patrolling the border with Mexico on a flight from Calexico International Airport, Calexico Field to Rockwell Field, San Diego, California, become lost in a storm, and land their Airco DH.4, DH.4B on a beach at Refugio de Guadalupe on Las Animas Bay in Baja California, Lower California. Lieutenants Cecil H. Connolly and Frederick D. Waterhouse survive for 19 days before they are murdered by Mexican fisherman for their pitiful belongings and their bodies buried. The destroyer USS Aaron Ward (DD-132), USS Aaron Ward is dispatched to retrieve the bodies and investigate the circumstances, returning the airmen’s remains to San Diego on 26 October 1919. The Governor of Baja California, Lower California, Esteban Cantú Jiménez, Esteban Cantu, declares that the aviators died either from thirst or were killed and their bodies partly dismembered by "ravenous" coyotes, both theories being rejected outright by Major R. S. Bratton, commander of the party that recovers the victims’ remains. Bratton asserts that the names of those involved in the murders are known both to him and to representatives of Gov. Cantu. Colonel H. L. Watson, commanding officer of Rockwell Field, states that the skull of one of the airmen had been fractured.

The International News Service reported that Crissy fell into a nose spin endeavoring to land. "Crissy, say onlookers, made too sudden and sharp a turn as he was landing and because he was close to the ground could not pull his machine out of the spin." "Sergeant Thomas, who was an observer and a reserve military aviator, was killed with Maj. D. H. Crissy, pilot, when their plane fell into a small pond near the Buena Vista landing field on the outskirts of Salt Lake City. Crissy and Thomas were just completing the first lap of the international air derby and were preparing to land. Thomas was seen to wave to men on the field as the plane descended. Suddenly it fell, nose down, into a pond of mud and water, 150 feet below. Both were unconscious when they were taken from the pond, and died when they reached the hospital. Sergeant Thomas enlisted 18 Feb. 1918, in Los Angeles. He was 22 years old and recently obtained rating as a reserve military aviator. He was stationed at Mather field and was recently engaged in forest fire patrol work in Oregon." Grief stricken at news of the death of his son, "W. C. Thomas of 951 Fresno Street [Los Angeles], today sought information as to the disposition of the body. Mr. Thomas telegraphed the Salt Lake police chief and the military authorities at Rockwell field but received no answer. Today, through the Evening Herald, he endeavored to learn details of the accident and what was done with his son’s body." The flying field at the Presidio is subsequently named Crissy Field.

Goldsborough walked several hours in search of aid. He "finally stumbled into the Paulson ranch and a rescuing party was sent out. The party found Wales dead." The body of Lt. Wales, accompanied by Lt. Goldsborough, arrived at Cheyenne on 11 October. Goldsborough stated that the blizzard was so bad that they could not see 20 feet ahead when they struck the granite side of the mountain. "By a weird fate the mountain was the only elevation of more than 100 feet in an area of over 200 square miles and the unlucky Wales also missed by only a few feet the Covet Pass, which splits the mountain and through which he might have passed safely." Lt. A. M. Roberts and his observer survive a close call when, in an effort to make up for lost time, Roberts chooses the direct route, over Lake Erie, between Buffalo, New York, Buffalo and Cleveland. His engine fails, and he has to ditch in the lake. Luckily, a passing freighter sees the crash and picks up the two men. An International News Service report identifies the crew of this aircraft as pilot Lieutenant H. T. Hynes, and his observer, and gives the location as "several miles out of Ashtabula Harbor."

;11 May :"Hampton, Virginia, HAMPTON, Va., May 11. - The army blimp, A-4 arrived safely at Langley Field late today after having drifted for an hour and a half over the ocean off Cape Henry with her engines dead. The craft drifted to sea before a four-mile northwest breeze until repairs were made when she turned her nose toward shore. The crew of five were none the worse for their experience. The engine trouble developed about 3:30 o'clock in the afternoon and for a time considerable anxiety was felt for the craft and its occupants by short stations and radio offices which kept in communication with the blimp. It was found unnecessary however to despatch 'sic''airplanes or other blimps to her assistance. Army officers refused to give out the names of the crew although it was said Lieutenant Olmstead was at the wheel during the flight." The pilot was probably Lt. Robert Stanford Olmsted, who will be killed on 23 September 1923, when the Army free balloon ''S-6'' is struck by lightning over the Netherlands during an international balloon race.

Entered at the last minute, the press dubbed the new entry, the Mystery Racer. Assigned to the second of three heats, and wearing race number 9, the close-fitting cowling over the Wright T-2 engine retained heat and caused the oil temperature to exceed its operating limit. Streaming smoke around the race course, the pilot was over Lake St. Clair, near Detroit when the red-hot engine failed. "The extreme low position of the lower wing was not conducive to ditching and the "Mystery Racer" flipped over and sank in the mud. The aircraft was written-off but the pilot emerged unscathed."

The machines burst into flames and were destroyed, and several men who attempted to rescue the men pinned beneath the wreckage were severely burned. The bomber, piloted by Captain Doyle, took the air to lead a formation of six planes and was 'banking' when the scout machine, in charge of Major Gearhart, rose swiftly and hit it in the rear. The other machines already in the air maneuvered out of the way and effected safe landings. It was announced tonight that a board of inquiry would investigate the accident." Fokker D.VII, ''AS-7795'', ex-German ''FF7795/18'', hit Martin NBS-1, ''AS-68491''.

:Martin GMT (Glenn Martin Transatlantic), USAAS ''62949'', (as identified in a 1972 article in ''Wings'' magazine) loses power on one of two Liberty engines while en route to Chanute Field, Illinois, is unable to stay aloft on one only, crashes. Pilot Maj. Bradley escapes injury, but Lt. Stanley Smith is fatally injured. Walt Boynes's account in ''Wings'' magazine gives the accident date as 5 March.Boyne, Walt, "''Martin's Marvels''", Wings, Granada Hills, California, October 1972, Volume 2, Number 5, page 60. A period report from the Associated Press states, however,: "New York City, NEW YORK, March 4. - Lieut. Stanley Smith, army air service, was killed and Maj. Follett Bradley was probably fatally injured when a giant Martin bomer 'sic''in which they had just left Mitchel Air Force Base, Mitchell Field 'sic''for Chanute Air Force Base, Chanute Field, Rantoul, Illinois, Rantoul, Ills. 'sic'' was forced down in Brooklyn. Four student mechanics, privates, who also were in the biplane escaped with only slight injuries owing to the skillful manner in which Major Bradley piloted the big bomer 'sic''to earth from 5,000 feet. The two officers were pinned under a wing of the machine, which, brought to earth on wheels, overturned when it struck a hillock. The mishap was due to a broken controlling rod." The Aviation Archeology site report matches the accident date, lists the pilot as Major Follett Bradley Sr., identifies the Martin as ''AS-62951'', and gives the crash site as Miller Street and Heigeman Avenue, Brooklyn, N.Y. Joe Baugher's serial number website adds that the aircraft had been modified to a Martin GMC with a 37-mm cannon in the nose, and that it carried McCook Field project number P110.

The dead are: Capt. W. R. Lawson, pilot, Langley Field, Va., Technical Sergeant Bidwell, Langley Field; Sergeant Wesley H. Rowland, Selfridge Field, Mich., and Civilian U. M. Smith, Bureau of Standards, Washington, D. C. The injured: Technical Sergeant F. B. Shaw, Selfridge Field, Mich. The accident happened as the men were taking off for Langley Field after having been here for several weeks. All the men in the plane had parachutes on their backs but were unable to use them because the plane was only a short distance from the ground when it dived. Brigadier General Billy Mitchell, William Mitchell, assistant chief of the air service, and Major L. W. McIntosh, commandant at McCook Field, were the first air service officers to reach the scene. Shortly after the accident General Mitchell took off for Bolling Field, Washington, D. C. As he passed over the scene of the disaster he dropped flowers into the river."

:1st Lts. Robert Stanford Olmsted and John W. Shoptaw enter U.S. Army balloon ''S-6'' in international balloon race from Brussels, despite threatening weather which causes some competitors to drop out. ''S-6'' collides with Belgian balloon, ''Ville de Bruxelles'' on launch, tearing that craft's netting and knocking it out of the race. Lightning strikes ''S-6'' over Nistelrode, the Netherlands, killing Olmsted outright, and Shoptaw in the fall. Switzerland's ''Génève'' is also hit, burns, killing two on board, as is Spain's ''Polar'', killing one crew immediately, second crewman jumps from 100 feet, breaking both legs. Three other balloons are also forced down.Maurer Maurer, "Aviation in the U.S. Army, 1919–1939", United States Air Force Historical Research Center, Office of Air Force History, Washington, D.C., 1987, , page 174.Vaeth, J.

;16 January :While moored at NAS Lakehurst, New Jersey, USS Shenandoah (ZR-1), USS ''Shenandoah'''s upper tail fin covering is ripped during a gale, and the sudden roll tears out her mooring tube from the Lakehurst mast. Damage to the nose deflates the first gas bag and holes the second. Zeppelin test pilot Anton Heinen rides out the storm and lands safely while the airship is being blown backwards. A period of repair is needed, not returning to service until 24 May 1924 (with reinforcements to the mooring assembly, nose, and fins), and a proposed Arctic expedition is scrapped.

;23 February

Ansley of the 111th Observation Squadron, Texas National Guard, crashes in Curtiss JN-4H, ''24-158'', (one source gives the type as a Curtiss JN-6) at Ellington Field, Texas, when he enters a tailspin during practice, but at insufficient altitude to recover, the airframe smashing into a pile of stacked lumber. The pilot dies later in hospital.

;21 March
:Martin GMB (Glenn Martin Bomber), USAAS ''64308'', ex-Post Office (possibly ''202''), ends cross-country flight to Parris Island, South Carolina, noses over when it hits unmarked ditch on the airfield. Pilot 1st Lt. (later Lieutenant General) Harold L. George reported later that "I also remember being told that it (Parris Island) was an exceptional landing field. It was except that the information had failed to inform me that the Marines had dug a trench across the field. This was not indicated by markers, or in any other way. I didn't know the trench was there until we stopped quickly." Airframe had only logged 99 hours when it was written off.

;27 March
:British-born 2nd Lt. Oscar Monthan (1885–1924) is killed when his Martin NBS-1 bomber, ''AS-68448'', of the 5th Composite Group, fails to clear baseball field backstop on take-off from NALF Ford Island, Luke Field, Ford Island, Oahu, Hawaiian Islands.

;15 September
:A Curtiss N-9 seaplane, equipped with radio control and without a human pilot aboard, was flown on a 40-minute flight at the Naval Proving Grounds, Dahlgren, Virginia. Although the aircraft sank from damage sustained while landing, this test demonstrated the practicability of radio control of aircraft.

;10 October :U.S. Army blimp TC-2 explodes over Newport News, Virginia, Newport News, Virginia, when a bomb it is carrying detonates. Two of five crew killed. "WASHINGTON, Oct. 10 – Lieutenant Bruce Martin of San Francisco was seriously injured with four other army men when the army blimp TC-2 was forced to the ground by the explosion of one of its bombs at Langley Field, Virginia." "Newport News, Virginia, NEWPORT NEWS, Va., Oct. 10 – Lieutenant Bruce H. Martin died at midnight as a result of injuries sustained at Langley Field this morning when a bomb carried by the U. S. Army blimp TC2 prematurely exploded, wrecking the craft and injuring the five members of its crew."

"Slight damage was done to the Shenandoah when the airship was brought to the ground last night. Officers at North Island this morning stated that one of the rear gondolas struck the ground slightly, but with sufficient force to strain two of the girders in the aft portion. The damage, it was said, is not serious, but on account of the mountains to be flown over on the flight to Fort Lewis (Washington), Camp Lewis, it was deemed best to make thorough tests to avoid any possibility of accident." "The work of repairing the strained girders continued all day yesterday (13 October)."

;11 October :"Philadelphia, Pennsylvania, PHILADELPHIA, Oct. 11 – Flying in excess of 150 miles an hour, the United States navy racing seaplane FTW fell 100 feet into the Delaware River, Delaware river 'sic''today and was completely wrecked. The pilot, badly injured, extricated himself." This was actually the Wright F2W-2, ''A7644'', which suffered from poor handling characteristics, the tremendous torque of its huge Wright T-3 Tornado liquid-cooled engine flipping the racer onto its back on landing during its first and only flight.

;16 October
:Emergency use of parachute — Following a mid-air collision over Coronado, California, Gunner William M. Coles, USN, of VF-1, made a successful emergency parachute jump from his Curtiss JN-4.

;18 November :"Laguna Beach, California, LAGUNA BEACH, Nov. 19. - Rescued from rough seas by two men in a rowboat when their seaplane landed 100 yards off of the rocky shores here, Lieutenants Douglas Powell and Charles Haltline of the USS New Mexico (BB-40), U. S. S. New Mexico are recovering from exposure and shock. One of the rescuers, who arose from a sick bed to aid the officers, is seriously ill, suffering from a relapse and exposure." The Associated Press reported: "SAN DIEGO, Nov. 18. - Lieutenants Douglas Powell and Charles G. Halpine, naval aviators, were rescued this evening off Laguna Beach, according to telephone messages from that place. The aviators left this city late today to fly to the battleship New Mexico at San Pedro, California, San Pedro. Off Laguna Beach Lieutenant Powell's machine, just repaired at North Island, developed engine trouble and Powell was forced to descend to the ocean. Lieutenant Halpine came down to aid him and managed to get a tow line to him. Darkness, however, set in and the two officers, not knowing exactly where they were, were forced to stop when they neared the breakers. There they shouted for help and the shout was heard by residents of the beach who assembled a battery of automobiles on a bluff and trained headlights on the aviators while two beach residents went out in a lifeboat and got the officers to shore." They were probably flying Vought UO-1 observation planes, which replaced other types aboard catapult equipped cruisers and battleships from 1923.Swanborough, Gordon and Bowers, Peter M., "United States Navy Aircraft since 1911", Naval Institute Press, Annapolis, Maryland, 1976, 1990, Library of Congress card number 90-60097, , page 433.
