BOAC Flight 781

BOAC Flight 781 was a scheduled British Overseas Airways Corporation passenger flight from Singapore to London. On 10 January 1954, a de Havilland Comet passenger jet operating the flight suffered an explosive decompression at altitude and crashed, killing all 35 people on board.

The aircraft, registered G-ALYP had taken off shortly before from Ciampino Airport in Rome, en route to Heathrow Airport in London, on the final leg of its flight from Singapore. After it exploded, the debris from the explosion fell into the sea near the island of Elba, off the Italian coast.

G-ALYP was the third Comet built. Its loss marked the second in a series of three fatal accidents involving the Comet in less than twelve months, all caused by structural failures; it followed the crash of BOAC Flight 783 near Calcutta, India, in May 1953, and was followed by the loss of South African Airways Flight 201 in April 1954, which crashed in circumstances similar to 781 after departing from Ciampino Airport.

Flight and accident

On the day of the accident, the Comet went through its routine preflight inspection in Rome, and was checked for "incidental damage"; none was found. The aircraft was therefore released to service. The same team of engineers a few months later examined South African Airways Flight 201 before its final flight.

Flight 781 departed from Rome at 10:31 CET (09:31 UTC) on 10 January 1954, on the final stage of its flight to London. At about 10:50 CEST, a BOAC Argonaut, registration G-ALHJ, piloted by Captain Johnson, which was flying the same route at a lower altitude, was in contact with Captain Gibson. During a radio communication about weather conditions, the conversation was abruptly cut off. The last words heard from Gibson were "George How Jig, from George Yoke Peter, did you get my—". Soon afterwards, witnesses saw wreckage falling into the sea.

Heathrow Airport initially listed Flight 781 as being delayed, but it was removed from the arrivals board at around 1:30 pm.
