Boom Supersonic, the American company building what promises to be the world’s fastest airliner, broke the sound barrier for its first time with a test flight in Mojave.

A supersonic jet built by US company Boom has broken the sound barrier for the first time since the Concorde during a test flight.

Denver-based Boom Technology's XB-1 demonstrator plane hit Mach 1.122 — 750 mph. It's the first independently developed supersonic jet. The company is also working on a supersonic passenger airliner.

The test flight took place in the same Mojave Desert area in California where Charles "Chuck" Yeager first broke the sound barrier in 1947.

A supersonic passenger jet dubbed the ‘New Concorde’ travelled faster than the speed of sound for the first time during a test flight today. Some 34,000ft above California ’s Mojave Desert, the XB-1 prototype reached speeds of 844 miles per hour – more than the 770mph speed of sound.

Boom Supersonic’s XB-1 demonstrator is set to exceed Mach 1 (770 mph) in a series of four-minute runs above the Mojave Desert in California. The US firm hopes it will pave the way for the introduction of passenger services early next decade.

Boom Supersonic CEO Blake Scholl said the Mach 1.7 Overture will keep the US aviation industry ahead of China in the commercial market.

The XB-1 demonstrator has broken the speed of sound, hitting Mach 1.1. It is the first civil supersonic aircraft in US history and the first to do so since Concorde was retired in 2003. That was an impressive sight. Just a short take-off roll and then XB-1 blasted into the sky and climbed steeply away from the runway.

Will Boom bring boom time back to supersonic travel? 'New Concorde' prompts revival talk - The aircraft developed by Boom Supersonic is the first independently funded jet to break the sound barrier

A sleek white aircraft has become the first independently developed jet to break the sound barrier. The XB-1 aircraft accelerated to Mach 1.05 within about 11 minutes of taking off Tuesday.
