Leslie P. Arnold
The first aerial circumnavigation of the world was completed in 1924 by four aviators from an eight-man team of the United States Army Air Service, the precursor of the United States Air Force. The 175-day journey covered over . The team generally traveled east to west, around the northern-Pacific Rim, through to South Asia and Europe and back to the United States. Airmen Lowell H. Smith and Leslie P. Arnold, and Erik H. Nelson and John Harding Jr. made the trip in two single-engined open-cockpit Douglas World Cruisers (DWC) configured as floatplanes for most of the journey. Four more flyers in two additional DWC began the journey but their aircraft crashed or were forced down. All airmen survived. In 1930, Australian Charles Kingsford Smith with a team of three others completed the first circumnavigation of the world by flight traversing both hemispheres, including the first trans-Pacific flight, from the US to Australia, in 1928. Kingsford Smith flew a Fokker F.V ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Chicago;Aero27G6
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

Douglas Cloudster
The Douglas Cloudster was a 1920s American biplane aircraft. It was the only product of the Davis-Douglas Company, and was designed to make the first non-stop flight coast-to-coast across the United States. Development The Davis-Douglas Company was formed in July 1920 to enable Donald Douglas to design and build an aircraft capable of non-stop flight coast-to-coast across the United States. David R. Davis provided the financing for the company. The resulting aircraft was the Cloudster, a single-bay equal-span biplane of wooden construction. It was fabric-covered except for the forward fuselage, which was covered with sheet metal. The aircraft was powered by a 400 hp (298 kW) Liberty V-12 piston engine. The Cloudster first flew on 24 February 1921, the aircraft broke the Pacific Coast altitude record by climbing 19,160 ft (5839 m) in 19 March that year, and attempted the coast-to-coast journey in June. The aircraft failed to make a non-stop journey due to e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staff Sergeant
Staff sergeant is a rank of non-commissioned officer used in the armed forces of many countries. It is also a police rank in some police services. History of title In origin, certain senior sergeants were assigned to administrative, supervisory, or other specialist duties as part of the staff of a British Army regiment. As such they held seniority over sergeants who were members of a battalion or company, and were paid correspondingly increased wages. Their seniority was indicated by a crown worn above the three sergeant's stripes on their uniform rank markings. National variations Australia In the Australian Army and Cadets, the rank of staff sergeant is being phased out. It was usually held by the company quartermaster sergeant or the holders of other administrative roles. Staff sergeants are always addressed as "Staff Sergeant" or "Staff", never as "Sergeant" as it degrades their rank. "Chief" is another nickname though this is only used for the company chief clerk (in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Martin (general)
Frederick Leroy Martin (November 22, 1882 – February 23, 1954) was an American airman best known as the first commander of the US Army Air Service's first aerial circumnavigation of the world in 1924 and as the commander of US Army Air Forces during the Attack on Pearl Harbor. Martin, a Major at the time, commanded the circumnavigation and piloted the Douglas World Cruiser ''Seattle'', until he crashed in a remote portion of the Alaskan Aleutian Peninsula, after which he relinquished command to Lt Lowell Smith. Martin received the Distinguished Service Medal for his part in the circumnavigation. By the beginning of World War II, Martin had been promoted to Major General and assigned to command the Hawaiian Air Force of two Wings (18th Bombardment Wing at Hickam Field and 14th Pursuit Wing at Wheeler Field) and outlying airfields at Bellows Field and Haleiwa Fighter Strip. Martin was temporarily relieved of command after the attack on Pearl Harbor, but was exonerated by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilots Of The 1924 Round The World Flight
An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls. Some other aircrew members, such as navigators or flight engineers, are also considered aviators, because they are involved in operating the aircraft's navigation and engine systems. Other aircrew members, such as drone operators, flight attendants, mechanics and ground crew, are not classified as aviators. In recognition of the pilots' qualifications and responsibilities, most militaries and many airlines worldwide award aviator badges to their pilots. History The first recorded use of the term ''aviator'' (''aviateur'' in French) was in 1887, as a variation of ''aviation'', from the Latin ''avis'' (meaning ''bird''), coined in 1863 by in ''Aviation Ou Navigation Aérienne'' ("Aviation or Air Navigation"). The term ''aviatrix'' (''aviatrice'' in French), now archaic, was formerly used for a female aviator. These terms were used more in the earl ...

Dead Reckoning
In navigation, dead reckoning is the process of calculating current position of some moving object by using a previously determined position, or fix, and then incorporating estimates of speed, heading direction, and course over elapsed time. The corresponding term in biology, used to describe the processes by which animals update their estimates of position or heading, is path integration. Dead reckoning is subject to cumulative errors. Advances in navigational aids that give accurate information on position, in particular satellite navigation using the Global Positioning System, have made simple dead reckoning by humans obsolete for most purposes. However, inertial navigation systems, which provide very accurate directional information, use dead reckoning and are very widely applied. Etymology The term "dead reckoning" was not originally used to abbreviate "deduced reckoning," nor is it a misspelling of the term "ded reckoning." The use of "ded" or "deduced reckoning" ...

Major General
Major general (abbreviated MG, maj. gen. and similar) is a military rank used in many countries. It is derived from the older rank of sergeant major general. The disappearance of the "sergeant" in the title explains the apparent confusion of a lieutenant general outranking a major general, whereas a major outranks a lieutenant. In the Commonwealth of Nations, Commonwealth and in the United States, when appointed to a field command, a major general is typically in command of a Division (military), division consisting of around 6,000 to 25,000 troops (several regiments or brigades). It is a two-star general, two-star rank that is subordinate to the rank of lieutenant general and senior to the rank of brigadier or brigadier general. In the Commonwealth, major general is equivalent to the navy rank of rear admiral. In air forces with a separate rank structure (Commonwealth), major general is equivalent to air vice-marshal. In some countries including much of Eastern Europe, major ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jack Northrop
John Knudsen Northrop (November 10, 1895 – February 18, 1981) was an American aircraft industrialist and designer who founded the Northrop Corporation in 1939. His career began in 1916 as a draftsman for Loughead Aircraft Manufacturing Company (founded 1912). He joined the Douglas Aircraft Company in 1923, where in time he became a project engineer. In 1927 he joined the Lockheed Corporation, where he was a chief engineer on the Lockheed Vega transport. He left in 1929 to found Avion Corporation, which he sold in 1930. Two years later, he founded the Northrop Corporation. This firm became a subsidiary of Douglas Aircraft in 1939, so he co-founded a second company named Northrop. Early life and entering aviation Born in Newark, New Jersey in 1895, Northrop grew up in Santa Barbara, California. In 1916 Northrop's first job in aviation was in working as a draftsman for the Santa Barbara-based Loughead Aircraft Manufacturing Company. After the outbreak of the First World War, N ...

Torpedo Bomber
A torpedo bomber is a military aircraft designed primarily to attack ships with aerial torpedoes. Torpedo bombers came into existence just before the First World War almost as soon as aircraft were built that were capable of carrying the weight of a torpedo, and remained an important aircraft type until they were rendered obsolete by anti-ship missiles. They were an important element in many famous Second World War battles, notably the British attack at Taranto, the sinking of the German battleship ''Bismarck'', and the Japanese attack on Pearl Harbor. Types Torpedo bombers first appeared immediately prior to the First World War. Generally, they carried torpedoes specifically designed for air launch, which were smaller and lighter than those used by submarines and surface warships. Nonetheless, as an airborne torpedo could weigh as much as , more than twice the bomb load of contemporary single-engined bombers, the aircraft carrying it usually needed to be specially designed ...
