1952 Moses Lake C-124 Crash
The 1952 Moses Lake C-124 crash was an accident in which a United States Air Force Douglas C-124 Globemaster II military transport aircraft crashed near Moses Lake, Washington on December 20, 1952. Of the 115 people on board, 87 died and 28 survived. The crash was the world's deadliest aviation disaster at the time, surpassing the Llandow air disaster, which killed 80 people. The death toll would not be surpassed until the Tachikawa air disaster, which also involved a Douglas C-124A-DL Globemaster II, killed 129 people. Accident The flight was part of "Operation: Sleigh Ride", a USAF airlift program to bring U.S. servicemen fighting in the Korean War home for Christmas. At around 18:30 PST, the C-124 lifted off from Larson Air Force Base near Moses Lake, Washington en route to Kelly Air Force Base, San Antonio, Texas. Just seconds after taking off, the left wing struck the ground and the aircraft cartwheeled, broke up, and exploded, killing 82 of the 105 passengers and 5 of t ...

Gust Lock
A gust lock on an aircraft is a mechanism that locks control surfaces and keeps open aircraft doors in place while the aircraft is parked on the ground and non-operational. Gust locks prevent wind from causing unexpected movements of the control surfaces and their linked controls inside the aircraft, as well as aircraft doors on some aircraft. Otherwise wind gusts could cause possible damage to the control surfaces and systems, or nearby people, cargo, or machinery. Some gust locks are external devices attached directly to the aircraft's control surfaces, while others are attached to the flight controls inside the cockpit. Safety A gust lock can pose a serious safety hazard if it is not disengaged before an aircraft's takeoff, because it renders the flight control inoperative. Many internal gust locks have a safety feature that locks out the aircraft's throttle or engine-start controls until removed and stowed. External-only gust locks typically lack this safety feature, and mus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevator (aircraft)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal stabilizer and ...

Accidents And Incidents Involving United States Air Force Aircraft
An accident is an unintended, normally unwanted event that was not directly caused by humans. The term ''accident'' implies that nobody should be blamed, but the event may have been caused by unrecognized or unaddressed risks. Most researchers who study unintentional injury avoid using the term ''accident'' and focus on factors that increase risk of severe injury and that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been caused by humans, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car wrecks are not true accidents; however English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Types Physical and non-physical Physical examples of accidents include unintended motor vehicle collisions, falls, being injured by touching something sharp or hot, or bumping into some ...

1952 In Washington (state)
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Aviation Accidents And Incidents In The United States In 1952
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes airplane, fixed-wing and helicopter, rotary-wing types, morphable wings, wing-less lifting bodies, as well as aerostat, lighter-than-air craft such as Balloon (aeronautics), hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet aircraft, jet which permitted a major form of transport throughout the world.

Arrow Air Flight 1285
Arrow Air Flight 1285R was an international charter flight carrying U.S. troops from Cairo, Egypt, to their home base in Fort Campbell, Kentucky, via Cologne, West Germany, and Gander, Newfoundland. On the morning of Thursday, 12 December 1985, shortly after takeoff from Gander en route to Fort Campbell, the McDonnell Douglas DC-8 serving the flight stalled, crashed, and burned about half a mile from the runway, killing all 248 passengers and 8 crew members on board. , it is the deadliest aviation accident to occur on Canadian soil. At the time of the crash, it was the deadliest aviation accident involving a DC-8; , it is the second-deadliest, behind the crash of Nigeria Airways Flight 2120 six years later. The accident was investigated by the Canadian Aviation Safety Board (CASB), which determined that the probable cause of the crash was the aircraft's unexpectedly high drag and reduced lift condition, most likely due to ice contamination on the wings' leading edges and uppe ...

Grand Canyon
The Grand Canyon (, yuf-x-yav, Wi:kaʼi:la, , Southern Paiute language: Paxa’uipi, ) is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is long, up to wide and attains a depth of over a mile (). The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery. Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted.

1956 Grand Canyon Mid-air Collision
The Grand Canyon mid-air collision occurred in the Western United States, western United States on Saturday, June 30, 1956, when a United Airlines Douglas DC-7 struck a Trans World Airlines Lockheed L-1049 Super Constellation over Grand Canyon National Park, Arizona. All 128 on board both airplanes perished, making it the first commercial airline incident to exceed one hundred fatalities. The airplanes had departed Los Angeles International Airport minutes apart for Chicago and Kansas City, Missouri, Kansas City, respectively. The collision took place in uncontrolled airspace, where it was the pilots' responsibility to maintain separation (aeronautics), separation ("see and be seen"). This highlighted the antiquated state of air traffic control, which became the focus of major aviation reforms. Flight history Trans World Airlines Flight 2, a Lockheed L-1049 Super Constellation named ''Star of the Seine'', with pilot in command, Captain Jack Gandy (age 41), First officer (aero ...

Lockheed L-1049 Super Constellation
The Lockheed L-1049 Super Constellation is an American aircraft, a member of the Lockheed Constellation aircraft line. The L-1049 was Lockheed's response to the successful Douglas DC-6 airliner, first flying in 1950. The aircraft was also produced for both the United States Navy as the WV / R7V and U.S. Air Force as the C-121 for transport, electronics, and airborne early warning and control aircraft. Development Beginning in 1943, Lockheed planned stretched variants of the Constellation family. The first was the L-049 with a fuselage lengthened by 13 feet (4 meters) and the second the L-749 stretched 18 feet (5.5 meters). Douglas launched a stretched version of its DC-6 airliner as a cargo transport, designated DC-6A, for both military and civilian operators. Douglas was soon to launch a passenger version (the DC-6B) of this new aircraft. The DC-6B could carry 23 more passengers than Lockheed's current production L-749 Constellation. In 1950, Lockheed had repurchased the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trans World Airlines
Trans World Airlines (TWA) was a major American airline which operated from 1930 until 2001. It was formed as Transcontinental & Western Air to operate a route from New York City to Los Angeles via St. Louis, Kansas City, and other stops, with Ford Trimotors. With American Airlines, American, United Airlines, United, and Eastern Air Lines, Eastern, it was one of the "Legacy carrier#Defunct legacy carriers, Big Four" domestic airlines in the United States formed by the Air Mail scandal, Spoils Conference of 1930. Howard Hughes acquired control of TWA in 1939, and after World War II led the expansion of the airline to serve Europe, the Middle East, and Asia, making TWA a second unofficial flag carrier of the United States after Pan American World Airways, Pan Am. Hughes gave up control in the 1960s, and the new management of TWA acquired Hilton Worldwide, Hilton International and Century 21 Real Estate, Century 21 in an attempt to diversify the company's business.

Douglas DC-7
The Douglas DC-7 is an American transport aircraft built by the Douglas Aircraft Company from 1953 to 1958. A derivative of the DC-6, it was the last major piston engine-powered transport made by Douglas, being developed shortly after the earliest jet airliner—the de Havilland Comet—entered service and only a few years before the jet-powered Douglas DC-8 first flew in 1958. Unlike other aircraft in Douglas's line of propeller-driven aircraft, no examples remain in service in the present day, as compared to the far more successful DC-3 and DC-6. Design and development In 1945 Pan American World Airways requested a DC-7, a civil version of the Douglas C-74 Globemaster military transport. Pan Am soon canceled their order. That proposed DC-7 was unrelated to the later DC-6-derived airliner. American Airlines revived the designation when they requested an aircraft that could fly the USA coast-to-coast non-stop in about eight hours. (Civil Air Regulations then limited domestic ...
