I came home from one detachment to APC in June 76 so the crew out there at the crash time must have taken over from us. I remember hearing about it at Odiham and being a Nav Insty at the time took particular interest in the details. As I remember it the fingers were all pointing at a pitch channel runaway in the autopilot as the system was prone to that. Even had a protection unit fitted eventually to prevent it happening.
The following year I was 'volunteered' to be part of the working party which disposed of the Puma's remains and those of the Harrier which also came to grief at around the same period. Two hours out into the Carribean on a navy landing craft and over the side with the lot!
