The 1952 Farnborough Airshow DH.110 crash was an air show accident involving a de Havilland DH.110 that killed 29 spectators, the pilot John Derry and the onboard flight test observer Anthony Richards. The DH.110, a prototype, was being demonstrated at the Farnborough Airshow when during a manoeuvre, the aircraft broke up. The cause was a faulty wing leading edge design. The DH.110 was grounded and strict safety procedures were subsequently enacted. After modifications to the design the DH.110 entered service with the Royal Navy as the de Havilland Sea Vixen. The event was the last British air show in which spectators were killed until the 2015 Shoreham Airshow crash in which 11 people died,〔(【引用サイトリンク】title=2/1978 Agusta Bell 206B, G-AVSN and DH82A Tiger Moth, G-ANDE, 15 May 1977 )〕 three of whom were reported to have been observing the event from the A27 rather than the designated spectators' area within the airfield. In addition, four people were killed while on a helicopter experience at the Biggin Hill Air Show in 1978. ==Breakup== The planned demonstration of the DH.110 on that day was nearly cancelled when the aircraft at Farnborough, an all-black night fighter prototype, became unserviceable. It had been taken supersonic over the show on the opening day. Derry and Richards left Farnborough to collect ''WG 236'' and flew it from Hatfield to Farnborough with just enough time to start their slot. Following a low-level supersonic flypast and during a left bank at about 450 knots (830 km/h) toward the air show's 120,000 spectators, the pilot started a climb. The outer starboard wing and, immediately afterward, the outer port wing broke off the aircraft, followed by both engines and the cockpit—the latter injuring several spectators. One engine broke into two sections and "ploughed into ... Observation Hill", injuring and killing numerous other spectators.〔 One eyewitness was Richard Gardner, then five years old. He recalled in adulthood:〔 Jet! When Britain Ruled the Skies. 1. Military Marvels. First broadcast BBC Four 22 August 2012 〕 Sixty-three years later, speaking on the BBC Today program in the wake of the Shoreham air disaster, author Moyra Bremner recalled her own traumatic experience. A huge bang silenced the crowd and was followed by "My God, look out" from the commentator. Bremner, standing on the roof of her parents' car, realized that an engine was heading straight towards her. It passed a few feet over her head, a "massive shining cylinder", and then plunged into the crowd on the hill behind. Following the accident the air display programme continued once the debris was cleared from the runway, with Neville Duke exhibiting the prototype Hawker Hunter and taking it supersonic over the show later that day. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1952 Farnborough Airshow DH.110 crash」の詳細全文を読む スポンサード リンク
