Published: 07:38 EDT, 4 October 2026 | Updated: 07:52 EDT, 4 October 2026 The death of an RAF Spitfire pilot who was killed when his plane crashed during a Battle of Britain Memorial Flight was 'very likely' caused by a decades-old piece of debris in the engine, a report has concluded.Squadron leader Mark Long, 43, died near RAF Coningsby in Lincolnshire on May 25, 2024.His plane went down at 1.16pm shortly after he took off to do a series of flypasts and a display for the memorial.Mr Long's family said in a statement issued by the MoD following his death: 'Mark lived his life with an unwavering passion with laughter, love and dedication to his family.'His talent for flying was there for all to see and his ability to connect to everyone he met was infectious. Mark will be cherished and deeply missed by us all.'He was flying a Supermarine Spitfire MK356, which was built at the Castle Bromwich Aircraft Factory, owned by the Morris Motors Company, in Birmingham in early 1944.The Defence Safety Authority published a report into his death to 'inform the military chain of command and the public of the findings of the inquiry and its recommendations to improve defence safety'.A service inquiry panel said 'engine performance data and witness statements align with what would be expected if the aircraft was experiencing fuel starvation'.
