The world of aviation took step backwards when the Concorde was withdrawn in 2003, but now we could leap forward again with a new business jet being developed by Boeing, Lockheed-Martin and Gulfstream, with help from NASA.
The X-54 will be able to reach speeds of 2,500-mph, or nearly double what the Concorde was capable of achieving. That will let you fly half way around the world from London to Sydney in just four hours, or about 16 hours less than the same route on a regular subsonic passenger jet.
