Dean,
I vividly remember the Mahe flypast and the 'G' meter readings. Yes the captain, Roger S. was rather prone to that sort of thing. As I recall he had done an exchange with the USAF on the 'Ski' 130. Later on he did another tour with the USAF on the F111 before becoming OC 35 on the Vulcan.
He died as Group Captain Air Cadets in a Chipmunk crash. His passenger was badly injured I believe.
I believe my pic on an earlier thread shows Jeff B. at the Lyneham families day and the extreme angle of bank mentioned.
