Whilst undergoing free-fall parachute training at Kingsfield
I remember doing that - still got my certificate 30 years later for my 10 jumps - though I never jumped again. Do you remember the old Rumanian(?) pilot who flew the aircraft for it?
Claimed to have flown for the Luftwaffe against the Russians and "bailed" out without a parachute over the Ukraniane by rolling off the back of the wing into a cornfield...
