Walter, I was with the crew in the last few hours before the flight. I walked out with Jon Tapper to the ac next to his and went flying on another sortie. I can ABSOLUTELY confirm that this was not any 'special' flight. It was as routine as any other one. I can confirm (and would do on oath) that they were unhappy with the aircraft allocated and wanted a Mk1 Chinook. In the hour before the flight, the crew had a coffee and Jon insisted that they went through FADEC emergency drills because he (quote) could not trust the bloody systems to keep the engines running. Once again, I would state this on oath if required. Those of us who knew Jon have the knowledge that he liked to do things by the book and didn't like risk taking. Forget the sabotage theories, this is wasted effort. Who knows??? the crew might or might not have been negligent, but there was no proof. This equals NOT GUILTY.
