It is worth mentioning that when BAH was sold to Mirror Group in '86 that fat lying thieving bastard maxwell saw an unparalelled opportunity to help himself to a large number of very fat long-term BA pensions, which sadly had to be transferred with the company for legal reasons. Even at that time there were grave doubts about the security of Mirror Group pensions, and tragically several scores of career pilots and others subsequently lost thier entire career's pensions to this criminal and many probably suffer to this day. Drowning was far too good for him.
The Chinook accident had no bearing on the end of BAH, the Mirror mugging was already in place by then, and (memory fails here) may well have actually happened by that time.
