thought this was a green energy plane without engines?
if only we could look into the past at other supersonic operations and see why they failed. Oh wait, we can. Besides being expensive and loud, you also have the little problem of spare aircraft. If the plane has a maintenance issue you can just book them on the next subsonic flight to London. They paid to go fast. So operators were having to fly empty spares around. Makes it hard to make money and be green flying empty airplanes.
