Boom Supersonic Completes Supersonic Flight

Boom Supersonic has achieved a significant milestone in developing its business, reaching Supersonic flight for the first time.

The company’s XB-1 demonstrator, which had been undergoing extended tests, has formally received the all-clear to fly at supersonic speeds.

The demonstrator aircraft completed such a flight at the Mojave Air & Space Port in California.

Flown by Chief Test Pilot Tristan “Geppetto” Brandenburg, the XB-1 could enter the supersonic-approved corridor at 35,290 feet before reaching Mach 1.122 (652 KTAS or 750 mph).

These speeds allowed the aircraft to break the sound barrier for the first time, marking a historic moment for the program’s long-term goal of building a full-scale supersonic airliner.

Ultimately, XB-1’s achievement of this feat moves away from traditional supersonic achievements, which typically involve militaries and governments developing such aircraft. In this case, it’s the first time an independently developed jet has broken the sound barrier.

Blake Scholl, the planemaker’s founder and CEO, said that the ability to operate a supersonic flight demonstrates that the technology for eventual adoption into a passenger commercial airliner has arrived.

Moreover, Scholl highlights how a small team of talented engineers could accomplish something that in the past took governments billions of dollars to complete.

Moving forward, Boom Supersonic will take these learnings and continue scaling up the technology seen on the XB-1 for the eventual adoption into the full-scale supersonic airliner known as Overture.

What Is Boom Supersonic Overture?

Boom Supersonic’s Overture is the full-scale aircraft the company wants to release, which airlines would commercially adopt.

Thanks to 100% sustainable aviation fuel (SAF), it aims to cruise at Mach 1.7, carrying 65–80 passengers over transoceanic routes while maintaining net-zero carbon emissions.

Boom Supersonic remains ambitious about its goals for this aircraft, but it also experiences significant scepticism about funding, the business case, and eventual adoption.

Despite this, the company powers and believes Overture will serve markets for decades and help redefine premium locations with faster leisure and business travel.
