Boeing's X-51 WaveRider has made aviation history by completing the longest ever supersonic combustion ramjet-powered flight. The unmanned aerial vehicle (UAV) flew for almost three and a half minutes in the skies off the southern California coast on Wednesday, reaching an altitude of about 70,000 feet and hitting hypersonic (Mach 5) speeds.
