waverider
A WaveRider is a hypersonic aircraft design that improves its supersonic lift-to-drag ratio by using the shock waves being generated by its own flight as a lifting surface, a phenomenon known as compression lift. To date the only manned aircraft to use the technique was the Mach 3 supersonic XB-70 Valkyrie.
The waverider remains a well-studied design for high-speed aircraft in the Mach 5 and higher hypersonic regime, although no such design has yet entered production. The Boeing X-51A scramjet demonstration aircraft was launched on Tuesday August 14, 2012. The X-51 successfully launched from the wing of a B-52 bomber, but after 16 seconds there was a problem with a control fin. The aircraft was unable to maintain its course, and the test was terminated before the X51-A's Scramjet engine was ignited. The craft then crashed into the Pacific Ocean.〔''X-51A Scramjet Flight Fails'', USAF〕
On May 3, 2013 it was extensively reported that the Boeing X-51 Waverider had launched successfully from and had accelerated using a rocket to at which point it separated from the rocket and ignited its Scramjet. It then accelerated further to and climbed to before shutting down its engine and intentionally crashing into the Pacific. It is reported the engine ran for in excess of 240 seconds and the aircraft covered over .
