- At 2100 GMT, NASA will launch its air-breathing X43-A Hypersonic Scramjet craft from on top a B52A at 12km where a rocket booster will take the X-43A to 33.5km at which point the experimental craft will be on its own to attempt Mach 10 speed. The craft will splash down into the ocean and it wont be recovered. This is the third launch by NASA of a scramjet. In June 2001, the first mission, the craft went off course and had to be disabled. In March 2004, the craft set a speed record of Mach 6.83. BBC NASA space.com
