New York to London in 90 minutes on a hypersonic jet? Hermeus says yes

A US start-up has revealed plans to develop a plane that will travel at five times the speed of sound, transporting passengers between New York and London in 90 minutes or less.

Aerospace company Hermeus Corporation, based in Atlanta, said it has obtained finance from seed funders and private investors to develop a plane that will travel at Mach 5 -- five times faster than Mach 1, the speed of sound.

If the project succeeds, it could revolutionize commercial transatlantic flights. Currently, air travel between London and New York takes more than seven hours.

The creators hope the aircraft will be capable of a range of 4,600 miles, with a cruising speed of 3,300 miles per hour.

Paul Bruce, senior lecturer in the Aeronautics Department at Imperial College London, sounded a note of caution.

"The biggest challenge for hypersonic flight is propulsion," he said. "We've sent small vehicles up and flown them hypersonically using scramjets, an advance type of jet engine. This is quite experimental and we've got a long way to go before we see these on a passenger aircraft.

At some point you may as well go ballistic, no cruising at all. hunter May 2019 #2

Hell, I'll vounteer - strap a scramjet on my ass!
