First Flight: March 22, 2024 Final Flight: February 10, 2025 Beginning with XB-1’s historic first flight on March 22, 2024, we steadily progressed through a series of 13 test flights at increasing speeds as XB-1 approached and ultimately exceeded Mach 1 on January 28, 2025 – making history in less than a year. | Boom Supersonic | Facebook
