At the inquest into the death of Capt Ben Babington-Browne (killed on 6 July 2009 in the crash of aircraft #146434), Lt Cdr William Robley of the UK Defence Helicopter Flying School confirmed that operating the aircraft at that altitude, temperature and weight meant that it was not the correct helicopter for that mission. When asked by the coroner: "Had you been there, would it have been obvious to you of the risks attached to using the Griffon helicopter in these conditions?" Lt Cdr Robley replied: "Yes." When asked: "Would you expect a competent pilot to have understood that this was not the correct helicopter for the mission?", Lt Cdr Robley replied: "It depended on the pilot's training; unless they have been trained, they are on a voyage of discovery."
