The Concorde

It's tragic that we've gone backwards in aviation in some ways in the past 30 years. The Concorde was a symbol of progress and it would be wonderful if I live to see the return of supersonic commercial aviation.

The fastest trip the plane did from New York to London was 2 hours and 52 minutes.

At supersonic speeds, a flight from New York to LA could take as little as two hours. There has been some progress -- like the X-59 -- in reducing the (very problematic) sonic boom.
