I have never forgotten the thrill of my first flight, it was in a Chipmunk flown by a Flt Sgt. After some 60 years it remains my best flight ever. After that nothing to speak of really, plenty of civ and trooping, pretty boring although the Comet Singapore - UK and back was a revelation after UK - Singapore by Britannia. I do regret not taking up the offer of a trip in the T4 on my final Harrier field deployment.
Lady SB beats me hands down: Shackleton, Hastings, Argosy and a 1574Flt Meteor.
