11 people have been injured after Singapore Airlines flight SQ308 from Singapore to London on 26 May encountered a very sudden loss of altitude in clear air turbulence. Debris was scattered throughout the aircraft. The 11 injured were treated upon arrival in Heathrow. The A380 (9V-SKH) stayed in London for 28 hours, and was unable to complete its scheduled return flight to Singapore as SQ319. Passengers booked on SQ319 were transferred to other flights. The aircraft flew back to Singapore the next day with flight number ‘SQ319D’. This flight had the suffix ‘D’, denoting ‘delayed’. It was operated as a ferry flight and had no passengers on board.
