I went on a Technical Tour of Concorde at the Aviation Viewing Park, Manchester Airport and it was an unforgettable experience. Four tour guides who answered every question thrown at them....these guys know that plane inside out. G-BOAC is the only Concorde with an accessible flightdeck and this really was the highlight of the tour. Ten minutes sitting up front. They say it's unique and it is. What a view !
I don't have a bad word to say about this tour. I would recommend it to anyone. There's a whole range of tours, something for everybody. All in all, this was the best £20 I've spent in a long time.
