Re: Bye bye Arctic
Concorde was stuffed by oil rising from $3 to $12 per barrel, which made it instantly uneconomic. It didn't help that it looked unlikely it'd be able to fly supersonic over land after all.
Unfortunately for the climate, none of this will stop subsonic flight. Our ability to release carbon from the ground at an economically viable price now is more than able to keep up with rising demand for the forseeable future, and aircraft are getting quieter.
