Beagle, I am guessing this one would have been around your time on the Bulldog?

IIRC, but Beagle please correct me, you undid your chute harness first ,before the safety harness at the end of the sortie? The enquiry believed he had released it prior to abandonment. When the 82 spinning loss took place we were all drilled on quick abandonment. One of the star pupil flyers and who later became a CFS instructor, 'banged out' in the hangar sans parachute, with the words, ' I think I had better do that again!' We thought it funny at the time.
