I was there from 74-77 as groundcrew, I was asked if I wanted to stay to the end but declined though not sure if that was a good or bad decision.
My memory was Mintoff and Gadaffi got in a deal over de-salination plants that Gadaffi would pay for in exchange for the use of Luqa with the RAF to leave.
I have some scanned in photos in a not very good condition (aged and discolored) taken of a Russian sub being loaded from a support ship in the Med, also some when we had to divert to Faro due to low fuel after a hairy attempt to land at Gibralter, and a couple of the Gibralter Hunters that decided to escort us in one day and play about on the wing tips, but I will let any aircrew who were on those trips add more detail if they so wish.
It was a good tour from my perspective, my wife who was of Maltese extraction was born in UK and had never been there and I never saw any trouble when there. Since then we have enjoy holidaying over there and the museum in Valetta used to have a whole section on 203 sqn, but I could not find it last time I went.
