Flying from New York to London in an hour – already from 2030?
The British space agency is researching a supersonic aircraft that transports passengers at five times the speed of sound. This would allow vacationers to fly from New York to London in an hour.

From New York to London in an hour? Or from Sydney to London in four instead of around 20 hours? It still seems to be science fiction, but the British space agency (UK Space Agency) believes that it will actually be possible in 2030. The government agency is currently working on a supersonic aircraft together with private companies.
The partner company Reaction Engines has developed an engine that the British space agency is sure will make a day trip between the metropolises a reality. Because the drive system with the name “SABRE“Can propel an airplane at Mach 5 – that’s five times as fast as sound. The engine already passed a crucial heat test under these conditions in August 2020, reports the British news portal “Express“.
Aircraft parts can withstand more than 1000 degrees
“It is fantastic to see Reaction Motors exceed this important milestone. This shows how pre-cooler technology can deal with the extreme temperatures associated with driving at five times the speed of sound, ”UK Science Secretary Chris Skidmore is quoted as saying.
During the last tests, the Reaction Engines pre-cooler successfully cleared airflow temperatures of more than 1000 degrees in less than 1/20 of a second. This could revolutionize air traffic, predicted Graham Turnock, head of the British space agency.
Recent tests on a heat exchanger and a hydrogen pre-burner were also positive, reports “Simple Flying“. The hydrogen pre-burner supplies the engine cycle with thermal energy during take-off and early flight. The HX3 heat exchanger, which is connected to the pre-burner, exchanges the heat between the combustion gas and helium. The HX3 withstood a maximum temperature of 1126 degrees – that was the hottest test by Reaction Engines so far.

Supersonic aircraft could also go into space
As the only supersonic aircraft to date for passenger transport, the Concorde covered the New York – Paris route from 1976 until it ceased operations in 2003 and needed three to three and a half hours for it. A supersonic aircraft from the British space agency could soon take this place. In addition, the UK Space Agency wants to use such aircraft outside of the earth’s atmosphere and thus create the next generation of framing devices.
