After leaving the RAF I worked at Heathrow for many years and managed to arrange a trip on Concorde on a dickie seat behind the Captain in the cockpit from JFK back to UK.
Although I had my camera with me I figured it was poor form just to take photos without asking, (anyway an unanounced flash might have upset people) so once the aircraft was settled in the cruise and everybody was relaxed, I asked the capt if he minded me taking a photo. He replied by getting out of his seat, putting me in it and taking a photo of me. Now how many of you have a photo of themselves in the drivers seat of Concorde at M2+ and goodness knows what flight level Well I have.
Never got a trip in a Lightning T bird though when I was a GD(FC)
