Been on 6 different Concordes...didn't fly anywhere but.
Sat in the coughpit for takeoff as a teenager on a Qantas 767 back in the good old days when you could visit the coughpit, but I dont think being in at take off was strictly allowed, family friend was the chief steward. Also got heaps of Business Class goodies hats, pins, bags, cards, amenities kits etc. Parents got champagne and business food etc.
Done the Cliffs of Dover Spitfire thing a few months back...minus the Spitfire...friends light plane.
Dream flight would be a Lancaster Bomber or a F18 or similar supersonic fighter.
