NASA is planning to build hypersonic jets that will fly through the Earth’s atmosphere and slash flight times around the world to a few hours at most.
The US space agency wants to manufacture a craft that would travel at five times the speed of sound and bring in a new age of aircraft akin to a turbo-charged Concorde.
Travelling at such speed would reduce the flight time from New York to Sydney to around two-and-a-half hours, from the 21 hours it is now.
The project is thought to be aimed at making a reusable aircraft that could fly to Mars but, as with previous space technology, it could have a huge impact upon passenger transport too.
