It's a bit of a moot point whether or not Concorde is the Greatest Civil Aircraft, but it's certainly the greatest piece of aviation engineering. I had the great privilege to fly on G-BOAB between JFK and LHR in March 1991; 3 hours 20 minutes against the clock, leaving New York at 0930 local and arriving Heathrow at 1750 local. Unless the boffins come up with a way of using some sort of alternative fuel we will never see her like again. Flying at 55,000 feet at Mach 2 is something 99.9% of the population can only dream about - the sky is dark blue and the curve of the Earth is distinctly visible. No turbulence, and apart from a slight surge when hitting the supersonic threshold there was absolutely no sensation of speed. The take-off was just about the best part of the trip, as it really threw nme back aaginst the seat - V2 was about 250knots - apart from the copious amounts of champagne on offer!
If you haven't tried it, don't knock it!!
