Some of the guys I used to work with, remember it coming in to Tulla a few years ago. If anyone else remembers the old articulated aerobridge on D4 (Intl finger), then you'll know what it was for, R1 on the Concorde.
EWL. I too am one who will always lament not having flown her. My only sighting of her was when they were grounded after the AF accident, whilst on approach into LHR.
I agree with the Colonel, if you can, DO IT! You'll keep the memories forever. My Dad remembers watching the Comet fly overhead on approach into MEB (I lived under it's flight path for 27 years!) and my Mum remembers a Spitty shooting down a Heinkel & doing a barrel roll over LPL during the war. Both events I would have loved to have seen, the latter with some reservation of course, but my folks will always remember them. But hurry, those seats are selling fast!
