The future of Air Force One: Could there one day be a US presidential plane that travels at five times the speed of sound?

Mach 5: Atlanta-based start-up Hermeus successfully tested a Mach 5 engine prototype in February 2020.

Fire it up: Now Hermeus has partnered with the US Air Force and the Presidential and Executive Airlift Directorate to work towards hypersonic travel for the Department of Defense.

20-seater: The Hermeus concept is for a 20-seater craft that could, potentially, fly between London and New York in 90 minutes.

Feeling supersonic: This artist concept shows Exosonic's low boom supersonic airliner converted into an executive transport aircraft.
