KLM Flight 633 was a passenger flight from Amsterdam to New York City. On September 5, 1954, immediately after takeoff from Shannon Airport, the plane ditched on a mudbank in the River Shannon. 28 people were killed in the accident.
[edit] Triton disaster
The Lockheed Super Constellation Triton (registration PH-LKY) was piloted by Adriaan Viruly, one of the airline's most senior pilots. After a refueling stop at Shannon, the plane took off for the transatlantic leg of the flight at about 2:30. There were 46 passengers and 10 crew on board.
Less than a minute after takeoff, the aircraft crashed into a mudbank of the river. Although the crash site was only about 2500 metres from the airport, no one was aware of the disaster. Rescue operations were only started after the plane's navigator, after having crossed the river, managed to reach the airport.
The aircraft was partially submerged, and at least one of the fuel tanks had ruptured during the crash. The fuel fumes rendered many passengers and crew unconscious, who then drowned in the rising tide. In the end, 3 crewmembers and 25 passengers perished.
[edit] Cause of the accident
The official investigation concluded that the accident was caused by an unexpected re-extension of the landing gear and the captain's incorrect behaviour in this situation. Viruly, who had been only one year from retirement, rejected the responsibility for the crash and was bitter about his subsequent treatment by KLM. In an interview he later stated that there simply had not been enough time to react.
