I was fortunate to do my time in Bahrain in 1968 on 8 Sqn, FGA9's and FR10's! I do remember having to change the anti-g valve when ever we did airfiring, the vibration fractured the bellows, not an easy job with the seat in on the line in the middle of summer!
Tim Thorne was a mear Flt Lt then! The SEngo was a pilot.
Happy days.
