May 1 was hot and windy in California’s high desert, but it didn’t seem to bother Boeing’s X-51A WaveRider for its final flight.

The experimental aircraft, powered by a scramjet engine designed to reach hypersonic speeds, did just that as it hit Mach 5, which is nearly 4,000 miles per hour. It flew for a total of six minutes, and three and a half of those minutes were with the scramjet engine, breaking its own record from its first flight in 2010 when the WaveRider flew for 143 seconds.
