A Texas billionaire is trying to build this supersonic private jet

The typical flight time from Los Angeles to Sydney, Australia is about 15 hours and 30 minutes.


On the Aerion AS2, a supersonic private jet currently in development, it would be just ten hours.

Aerion said on Monday that it plans to have the AS2, a business jet that will be able to fly Mach 1.5, faster than the speed of sound, ready for flight by 2021, and approved for sale just two years later.

The Concorde was retired in 2003, so no passenger airplane currently flies the speed of sound.
