“Boom’s XB-1 supersonic demonstrator aircraft successfully executed its second flight at the Mojave Air & Space Port in Mojave, California. Following its historic first flight in March 2024, XB-1 continues to progress through its flight test program, targeting supersonic flight by the end of the year…

During this flight, XB-1’s landing gear was successfully retracted and extended for the first time, which is typical of second test flights. Additional objectives for this flight test were for the XB-1 team to assess aircraft handling qualities and activate a new digital stability augmentation system – or roll damper – for the first time. This roll damper was implemented to improve handling qualities based on learnings from first flight.

In addition, tufting was applied to XB-1’s right wing to observe and evaluate the direction and strength of airflow across the wing, verifying its aerodynamic characteristics. XB-1 flew for approximately 15 minutes, reaching an altitude of 10,400 feet and speeds of 232 knots (277 mph).”
