Boom boasts supersonic success with XB-1
More than 20 years since the final Concorde flight, is a small US start-up now on course to bring back supersonic air travel? TIM ROBINSON FRAeS and JOE COLES debrief Boom’s XB-1 test pilot and consider the next steps in civil supersonics.
How Boom’s XB-1 cracked the code for silent supersonic flight
American firm Boom Supersonic’s XB-1 has once again reached supersonic speeds without producing an audible boom, following its milestone flight on January 28 this year. The aircraft is the first piloted non-military plane to break the sound barrier since Concorde’s retirement in 2003.
Boomless Cruise: How Boom Supersonic’s XB-1 breaks the sound barrier quietly

This Company Is Taking the ‘Boom’ Out of Supersonic Flight
Boom Supersonic’s XB-1 creates a sonic boom inaudible from the ground below when flying at the exact right speed and altitude.
How the XB-1 aircraft went supersonic without a sonic boom
When the experimental XB-1 aircraft achieved supersonic speeds on a test flight, it did not create a disruptive sonic boom – thanks to a physics phenomenon called the Mach cutoff
Boom flies supersonic without sonic boom
Boomless Cruise is based on physics known as the Mach cutoff, in which a sonic boom refracts in the atmosphere and never reaches the ground. This was achieved by breaking the sound barrier at a higher altitude, with the exact speeds varying based on the atmospheric conditions.
