Aviation Accident Summary Archive

On August 2, 1947, a British South American Airways Lancastrian named Star Dust disappeared while crossing the Andes during a flight from Buenos Aires to Santiago. The aircraft's final Morse code transmission ended with the mysterious word STENDEC, repeated twice. Despite extensive searches, no trace of the aircraft was found for over 50 years. In 1998, mountaineers discovered wreckage on the Tupungato Glacier at 15,000 feet. Subsequent investigations concluded the crew likely encountered a powerful jet stream, a phenomenon poorly understood at the time, which significantly reduced their ground speed. Believing they had already cleared the mountain peaks, the crew began a premature descent in heavy cloud cover and struck the side of Mount Tupungato at high speed.

Controlled Flight Into Terrain (CFIT)

On July 29, 1947, a Douglas C-47 Skytrain carrying medical supplies was shot down by two Dutch Curtiss P-40 Kittyhawk fighters while on final approach to Maguwo Airfield. The flight, chartered by Indonesian nationalists to transport Red Cross supplies from Singapore, had been granted safe passage by both British and Dutch authorities. Despite this, the Dutch fighters intercepted the aircraft, destroying the left engine and causing it to crash into a paddy field in Ngoto. Eight of the nine people on board were killed, including high-ranking Indonesian air force pioneers and the Australian pilot. The incident occurred during the Indonesian National Revolution, shortly after Indonesian biplanes had conducted retaliatory raids on Dutch positions.

Military Action

Pan Am Flight 121, the Clipper Eclipse, crashed in the Syrian Desert following a catastrophic engine failure and subsequent in-flight fire. While en route from Karachi to Istanbul, the number 1 engine was shut down due to a rocker arm failure. The remaining engines overheated under the increased load, eventually leading to a fire in the number 2 engine. The fire intensified, causing the engine to separate from the wing and severing fuel lines. During an attempted emergency landing in total darkness, the aircraft struck the ground and ground-looped, breaking apart and killing 14 people. The accident is notable for the survival and heroism of Third Officer Gene Roddenberry, who later created the Star Trek franchise.

Mechanical Failure

A Douglas DC-4 crashed into a mountain ridge while attempting an alternate approach into Washington, D.C. during poor weather. The flight had been cleared for a descent to 2,500 feet on a newly approved route for which no minimum safe altitude had been established by the airline or the regulator. The aircraft struck Lookout Rock at approximately 1,425 feet, killing everyone on board. The accident was the second-deadliest in U.S. domestic aviation history at the time.

Controlled Flight Into Terrain (CFIT)

Eastern Air Lines Flight 605, a Douglas C-54B Skymaster, suddenly entered a steepening dive from its cruising altitude of 4,000 feet and crashed into a wooded area near Bainbridge, Maryland. All 53 people on board were killed in what was, at the time, the deadliest aviation accident in United States history. Despite an intensive investigation, the Civil Aeronautics Board could not determine the definitive cause of the dive, though evidence suggested the empennage may have failed during the descent.

Unknown

United Air Lines Flight 521 failed to become airborne during a takeoff attempt on a short runway at LaGuardia Airport. The aircraft overran the runway, crossed the Grand Central Parkway, and plunged into a pond before exploding. The investigation focused on the pilot's failure to release the gust locks or a late decision to abort the takeoff under changing wind conditions.

Pilot Error

A Delta Air Lines Douglas DC-3C carrying senior company executives was struck from above by a Vultee BT-13 Valiant while both aircraft were on final approach to Runway 5 at Muscogee County Airport. The BT-13 pilot failed to fly a standard traffic pattern and did not maintain a lookout for other aircraft. Upon impact at an altitude of approximately 10 feet, the two aircraft became wedged together. The DC-3 pilot applied full power, causing the entangled wreckage to climb to 150 feet before stalling and crashing. All eight occupants of the DC-3 and the sole pilot of the BT-13 were killed.

Pilot Error · Multi-aircraft

An Avianca Douglas DC-4 crashed into Mount El Tablazo while en route to Bogotá, killing all 53 people on board. The aircraft was flying in heavy fog when it struck the mountain at an elevation of approximately 10,500 feet. The accident was the deadliest in Colombian history at the time and involved several high-ranking oil industry executives.

Controlled Flight Into Terrain (CFIT)

A KLM Douglas DC-3C crashed shortly after takeoff from Copenhagen Kastrup Airport when the flight crew attempted to depart with the elevator gust locks still engaged. The aircraft entered a steep 45 degree climb immediately after rotation, stalled at an altitude of approximately 100 meters, and plunged into a snow covered field near the airport perimeter where it was destroyed by impact and fire. All 22 people on board were killed, including Prince Gustaf Adolf of Sweden and American opera singer Grace Moore. The investigation determined that a ground technician had installed wooden lock pins to protect the control surfaces from moderate winds during the stopover, but failed to remove the elevator pins before departure. The flight crew also failed to perform a pre-flight walk-around or a control check that would have identified the blockage.

Human Factors (Operational)

A Spencer Airways Douglas C-47A crashed during takeoff from Croydon Airport after the pilot attempted to lift off in a semi-stalled condition while heavily loaded. The aircraft failed to maintain altitude, banked sharply, and collided head-on with a parked, empty Czechoslovak Airlines (CSA) C-47. Both aircraft were destroyed by fire. The investigation revealed the flight was operating without a valid Certificate of Airworthiness or Certificate of Safety, and the pilot, who was also the airline's owner, lacked sufficient experience on the Dakota type and was likely suffering from fatigue.

Pilot Error · Multi-aircraft

Eastern Air Lines Flight 665 crashed into a knoll in the Blue Ridge Mountains during a rainstorm after the pilot attempted a descent without positively determining the aircraft's position. The flight was approximately 63 miles northwest of the Winston-Salem radio range station when it struck terrain at an elevation of 2,479 feet. Investigators determined that the pilot had made multiple erroneous navigation reports, believing the aircraft was over Greensboro and Winston-Salem when it was actually far to the northwest, and had deviated from standard company route procedures.

Pilot Error

A United States Navy Martin PBM-5 Mariner, callsign George 1, crashed into a ridge on Thurston Island during a blizzard while supporting Operation Highjump. The aircraft struck the terrain and caught fire, resulting in the immediate deaths of two crew members and the death of a third two hours later. The six survivors endured extreme Antarctic conditions for 13 days before being located by a search plane from the USS Pine Island. The rescue operation involved multiple vessels of the expedition; while the survivors were ferried back to the Pine Island, the critically injured pilot Ralph LeBlanc was transferred to the USS Philippine Sea for emergency surgery, including the amputation of both legs due to severe frostbite.

Weather

TWA Flight 6963 crashed during an approach to Shannon Airport after the aircraft's altimeters provided false readings due to a maintenance error. The Lockheed L-049 Constellation, named Cairo Skychief, struck the ground on the island of Inishmacnaughton while the crew believed they were at a safe altitude. The impact destroyed the aircraft and triggered a fire, resulting in the deaths of nine people. Investigators discovered that the static pipelines for the flight instruments had been incorrectly assembled, causing the altimeters to indicate the aircraft was higher than its actual position.

Human Factors (Maintenance)

A Douglas Dakota 3 crashed onto the roofs of two semi-detached houses in South Ruislip shortly after taking off from Northolt Aerodrome. Despite the aircraft coming to rest atop residential buildings and being a total loss, all five people on board and all residents on the ground survived without injury. The accident was caused by a significant accumulation of snow and ice on the wings during a long departure delay, which disrupted airflow and prevented the aircraft from gaining altitude.

Weather

A United States Air Force C-53D Skytrooper carrying high-ranking officers and their families crash-landed on the Gauli Glacier in the Swiss Alps during a flight from Austria to Italy. The crew became disoriented in instrument meteorological conditions and were forced down by a sudden katabatic wind, resulting in a controlled flight into terrain at 10,990 feet. Despite the high-speed impact, all 12 occupants survived due to the cushioning effect of deep snow. The subsequent rescue operation, which culminated in the first-ever alpine rescue using aircraft equipped with skis, is credited with improving post-war U.S.-Swiss relations and leading to the birth of modern Swiss air rescue (Rega).

Controlled Flight Into Terrain (CFIT)

On 14 November 1946, a KLM Douglas C-47A crashed during its third landing attempt at Amsterdam Schiphol Airport in dense fog, killing all 26 people on board. The aircraft stalled and struck the ground at a steep angle while the pilot was performing a sharp left turn to align with the runway at low speed. Investigators determined that the captain was not sufficiently familiar with the DC-3's vulnerability to asymmetrical stalls during low-speed steep turns, nor was he sufficiently proficient in low-visibility approaches.

Pilot Error

An American Overseas Airlines Douglas DC-4, named Flagship New England, crashed into a ridge shortly after taking off from Stephenville, Newfoundland. The flight had diverted to Stephenville due to poor weather at its planned stop in Gander. During a pre-dawn departure from Runway 07, the pilots failed to execute a required right-hand turn to avoid rising terrain. The aircraft continued straight ahead in darkness and overcast conditions, striking a steep ridge at an elevation of 1,160 feet. All 39 people on board, many of whom were the families of U.S. servicemen, were killed.

Pilot Error

A Sabena Douglas DC-4 crashed into a densely wooded bog 35 kilometers southwest of Gander during a visual approach in poor weather conditions. The aircraft was on a proving flight from Brussels to New York with a scheduled refueling stop at Gander. In an attempt to establish visual contact with the ground under a low cloud base, the pilot descended too far and struck trees. The accident is historically significant as the first major civilian aviation rescue to utilize helicopters, which were disassembled and flown to Newfoundland specifically to evacuate survivors from the inaccessible terrain.

Controlled Flight Into Terrain (CFIT)

A Douglas C-47A Skytrain crashed into the eastern face of Mistberget during an approach to Oslo Airport, Gardermoen, killing three crew members. The investigation determined the aircraft was under pilot control when it struck trees at an altitude of 620 meters (2,030 feet) while heading south. The accident was classified as a controlled flight into terrain (CFIT) resulting from the crew beginning their descent too early, exacerbated by insufficient training in radio range navigation and missing onboard equipment.

Controlled Flight Into Terrain (CFIT)

A Lockheed L-049 Constellation on a training flight suffered a catastrophic in-flight fire caused by electrical arcing in the baggage compartment. The fire produced intense smoke that filled the cockpit, blinding the crew and making it impossible to maintain control of the aircraft. The plane crashed in Bern Township, killing five of the six crew members on board. The accident led to a landmark 42-day grounding of the entire Lockheed Constellation fleet for safety modifications.

In-flight Fire

A converted B-17 Flying Fortress bomber, operating as a military transport for service members returning from World War II, crashed into the southern face of Mount Tom during a heavy rainstorm. The aircraft was attempting to land at Westover Field after circling for nearly two hours due to poor visibility and engine trouble. All 25 occupants—comprising 8 crew members, 15 Coast Guardsmen, one Red Cross official, and one U.S. Public Health Service doctor—were killed when the aircraft struck a stone ledge at an elevation of approximately 900 feet and exploded.

Controlled Flight Into Terrain (CFIT)

A U.S. Army B-17 Flying Fortress crashed into White Hill near Fairfax, California, after the crew became lost in dense fog and the aircraft suffered fuel exhaustion. The aircraft was en route to Hamilton Army Airfield when the pilot reported being low on fuel. Due to a mutual misunderstanding of the aircraft's position, Naval Air Station Oakland operators, believing the plane was over their station, instructed the crew to descend to 1,500 feet for radar identification. However, the aircraft was actually over mountainous terrain in Marin County. The bomber's engines quit due to fuel starvation, and it struck the hillside at approximately 140 mph, resulting in three fatalities and serious injuries to the remaining crew.

Controlled Flight Into Terrain (CFIT)

A United States Army Air Forces C-47 transport carrying high-ranking Chinese Communist Party (CCP) officials crashed into Heicha Mountain during a flight from Chongqing to Yan'an. The aircraft had stopped to refuel in Xi'an and encountered poor visibility and mountainous terrain during its final descent. All 17 occupants, including General Ye Ting and CCP General Secretary Bo Gu, were killed. The event, known in China as the April 8 Incident, significantly impacted the CCP leadership and their ongoing negotiations with the Kuomintang.

Controlled Flight Into Terrain (CFIT)

A Vickers Wellington bomber crashed into a residential area in Rabat, Malta, during a fighter affiliation training exercise, killing all four crew members and 16 civilians on the ground for a total of 20 fatalities. The aircraft was performing evasive maneuvers against a Supermarine Spitfire when it entered a port turn and descended at a 20 degree angle until impact. A magisterial inquiry suggested that a hydraulic fluid leak may have released toxic fumes, incapacitating the crew and leaving them unable to control the aircraft or transmit a distress call.
