I wonder if there will be any footage available online?A B-52 bomber will lift the wingless unmanned jet from US Edwards Air Force Base in California to 50,000 feet (15,250m).
The craft will then be dropped, and after a free fall of about four seconds, its engine is supposed to ignite.
X-51A WaveRider should then climb to 70,000ft (21,300m) and eventually reach Mach 6.
Should be pretty impressive watching something hit Mach 6.
Not quite ready for manned test flights thenThe WaveRider test flight is expected to last for about five minutes. At the end of it, the aircraft will break into pieces and fall into the Pacific.
