- description: The US Air Force planned a key test of an experimental aircraft designed to fly at six times the speed of sound, or about 6,500kph. The unmanned X-51A WaveRider, the military's latest attempt at hypersonic flight, was expected to reach Mach 6 after it is dropped by a B-52 bomber and takes flight off the Southern California coast. Engineers hoped the X-51A would sustain its top speed for five minutes, twice as long as it has gone before. The X-51A WaveRider could become the basis for much faster commercial flights and a new tool for military use. Al Jazeera's Mark Orchard reports.
