This hypersonic hydrogen jet could fly from London to New York in 90 mins

Flying across the world from Europe to Australia currently takes around 20 hours in a regular passenger jet. But Swiss startup Destinus is looking to slash that time to just four hours — by taking jet travel to hypersonic speeds.  Founded by Russian-born physicist and serial entrepreneur Mikhail Kokorich, Destinus is developing a prototype hydrogen-powered aircraft capable of travelling at Mach 5 and above. That’s five times the speed of sound: over 6000 kph.  This would take you from Frankfurt to Sydney in just over four hours.
