May I suggest that anyone who still has questions about the crash obtain a copy of JM Ramsden's booklet "Chinook Doubts - A Pain Person's Guide," which marshalls all the facts surrounding the accident in an easily digestible form. It costs £10 and is available from Ramsden himself at 20, Townsend Drive, St Albans, Herts AL3 5RQ. Ramsden is an eminently qualified authority with no vested interest in absolving the dead, and he has exhaustively researched as many aspects of this accident as are possible.
