A JET dubbed 'the son of Concorde' has achieved a new speed record in major progress towards 3.5 hour flights from London to New York.
Supersonic Boom's XB-1 jet has been put to the test to try to bring back superspeed travel between the UK and US.
The XB-1 is essentially the "test platform" for the Boom Overture, New Atlas reports.
If tests are successful a supersonic airliner carrying between 64 and 80 passengers could be available from 2029.
Creators want the aircraft to reach Mach 1.7 (around 1,300 mph).
