Never flew in the Concorde but I did get to watch it take off from flight line at CDG a couple of times. One of the most beautiful planes to watch ascend.
I can't say that I'd want to fly in it, I feel like I'd be disappointed. I have family who are U.S. Air Force F-16 and F-15 fighter pilots and have been lucky enough to get in a ride in the back seat of the F-15. Talk about an amazing takeoff. ^
