Boeing's X-51 WaveRider Jet Crashes In Mach 6 Attempt

An anonymous reader writes "Boeing's experimental hypersonic X-51 WaveRider aircraft crashed today during an attempt to hit Mach 6 while traveling over the Pacific Ocean. The cause of the crash was a faulty control fin, which compromised the test before the Scramjet engine could be lit. A vehicle traveling at Mach 6 (six times the speed of sound) would be able to travel from New York to London in just one hour."
