engine turbine failure. During the previous grounding of all Comets, modifications had been made to the aircraft, including Yoke Yoke, that seemed to eliminate this possibility. After an extensive multi-year investigation chaired by Lionel Cohen, Baron Cohen, the official document of findings was released by the Ministry of Transport and Civil Aviation, on 1 February 1955, as Civil Aircraft Accident Report of the Court of Inquiry into the Accidents to Comet G-ALYP on 10 January 1954 and Comet G-ALYY on 8 April 1954.The joint investigation of this accident, and of BOAC 781, revealed manufacturer design defects (square windows) and metal fatigue that resulted ultimately in the explosive decompression that caused both accidents. In popular culture The events of Flight 201 were included in "Ripped Apart", a Season 6 (2007) episode of the Canadian TV series Mayday (called Air Emergency and Air Disasters in the U.S. and Air Crash Investigation in the UK and elsewhere around the world). This special episode examined aviation emergencies that were caused by pressurization failure or explosive decompression; the episode also featured BOAC Flight 781.
