The Boeing X-51A WaveRider hypersonic vehicle, powered by a Pratt & Whitney Rocketdyne scramjet engine, achieved aviation history this week by making the longest ever combustion ramjet-powered supersonic flight. During its first jaunt, the craft reached 70,000 feet and an approximate speed of Mach 5 on a 200-second flight over the Pacific Ocean on May 26 at 10 a.m. before it was purposely crashed into the water.
