When I was a kid, I always wanted to ride on the Concorde.
The Concorde, for those not familiar with it, was a supersonic badass Passenger Plane Of The Future tested and built in the 1960's and operated through the early 2000's. It had a cruising altitude nearly twice that of normal airliners, could complete long distance routes over twice as quickly as any other passenger jet on the planet, and had this sweet retro-futurist sci-fi pulpy look to it that wouldn't look out of place on a Fantastic Four cover from 1962.
It was cool and new and also an utterly stupid waste of time and money aggressively subsidized by the British and French governments for way, way too long.
