Boom’s XB-1 demonstrator is the first independently developed supersonic jet, and the first civil supersonic jet built in America. Since XB-1 first flew in March of 2024, it has been through a rigorous program of 11 test flights at steadily increasing speeds.
And now, XB-1 is ready to fly supersonic!
Live from Mojave
Witness the historic moment when XB-1 breaks the sound barrier live, in real time. Our goal is to bring supersonic to everyone, starting with sharing XB-1’s first supersonic flight via livestream.

*Please note that flight date and time may change for mission safety or weather considerations.
The Countdown is On
Start the countdown with us and tune into the livestream to watch the moment XB-1 accelerates to Mach 1 for the first time. The livestream is made possible by flying a Starlink unit in our T-38 chase plane, enabling us to watch XB-1 in-flight with a one-of-a-kind air-to-air view.
Meet the Hosts
The supersonic livestream will be hosted by former Chief Concorde Pilot for British Airways, Mike Bannister. No one knows supersonic travel better than Bannister, who flew almost 7,000 supersonic hours in the Concorde.
“Even people who have flown supersonic hundreds of times never stop getting excited about it,” Bannister says.
Bannister will be joined by expert members of the XB-1 team, Chief Flight Test Engineer Nick Sheryka and Boom advisor and former Chief Engineer Greg Krauland to talk through each key moment of the flight.
What to Expect During Supersonic Flight
Boom’s Chief Test Pilot Tristan “Geppetto” Brandenburg shares how he has prepared and what to expect during XB-1’s supersonic flight: what’s the planned flight path, exactly how fast will XB-1 go, and what about the sonic boom? Find out in this Q&A with the pilot who will be at the controls during supersonic flight.
The Road to Supersonic: By the Numbers
The XB-1 team brings over one thousand years of combined aerospace experience and has devoted nearly two years to ground and flight testing XB-1 in Mojave, CA—all driven by one mission: supersonic flight.
Here’s what the journey has looked like, by the numbers:
- 1,049 years of combined aerospace expertise
- 22 months of ground & flight testing
- 11 successful flight tests before supersonic
- 450 minutes total flight time
- 176 games of pre-flight pickleball
- 19,760 hours reviewing ground and flight test data
- 156 total hours in data review meetings
- 75 briefs & debriefs
How Do You Make a Livestream Happen at Supersonic Speeds?
Starlink might change the game for future flight test efforts and other small aerospace ventures worldwide. Find out how our team adapted and tested a $500 Starlink Mini antenna to capture the XB-1 test flight livestream, and potentially open up a whole new world for flight test telemetry. Spoiler alert: it involves a 1995 Mazda Miata.
