The XB-1Boom Supersonic’s supersonic demonstrator aircraft, has taken off again, successfully completing its third test flight on September 13. Just a few weeks after its second second flightThis marks a further step towards the goal of reaching supersonic speeds before the end of the year. The feat was performed at the Mojave Air and Space Port in California by Tristan “Geppetto” Brandenburg, Boom’s chief test pilot.
How was the XB-1 test flight?
During this test, the Boom team continued to evaluate the performance of key systems and systematically expand the flight envelope. The pilot took the XB-1 to maximum pitch and yaw attitudes, anticipating conditions to be expected in future flights. These maneuvers were performed at higher altitude to ensure safety in the event of any unexpected behavior of the aircraft.

Additionally, the operation of the environmental control system (ECS), which is vital for maintaining cabin temperature and pressurization, was verified. This step is crucial to ensure optimum performance at higher altitudes, where pressure and temperature are more extreme. The landing gear was also tested at a higher speed than in the previous flight, reaching 215 knots. This is the second step in the sequence to reach the maximum safe speed of 225 knots for landing gear climb and descent operations.
On the road to supersonic speed
The XB-1 test program is progressing toward supersonic flight, with a test phase that calls for a total of 10 additional flights before reaching speeds above Mach 1. Boom Supersonic received the first Special Flight Authorization (SFA) from the Federal Aviation Administration (FAA) to exceed the speed of sound, a crucial green light for supersonic operations.
The flights will be conducted at the R-2508 Complex, using air corridors known for advanced aeronautical operations.
Not only does this aircraft represent a return to supersonic speed, but it also paves the way for the design and development of OvertureBoom’s supersonic business jet. The XB-1 uses cutting-edge technology, from its digitally optimized aerodynamic design to carbon fiber composites and augmented reality systems that enhance visibility during takeoff and landing.
This progress comes two decades after the retirement of Concorde, marking a resurgence of supersonic flight in the civilian arena. Boom’s team expects that, upon successful completion of testing, Overture will be the next big leap forward in commercial aviationenabling travel at speeds that seemed to be a thing of the past.
