Ran across some links claiming that an air/spacecraft has been developed by the US Air Force and Lockheed with capable of speeds approaching mach 50. Can't seem to find pictures or drawings of this craft. Anyone else heard of this craft? Here are some links;
Would love to see additional information on this craft if it really exists.

I seriously doubt that anything manmade could get above Mach 21-22 without disintigrating when it hits the atmosphere, using current technology.

Mach 50 is impossible for atleast 30 more years.
The idea of creating a plasma field around an aircraft is not a new one either. Such a possibility was thoroughly studied by both Russians and Americans. This was done for very different reasons, however. Aircraft designers want to use a plasma shield generator on hypersonic aircraft. In this application, plasma may be generated by a powerful plasma laser and will act as a heat shield for an aircraft. There are plans to use such a system in conjunction with a magnetohydrodynamic (MHD) propulsion to achieve velocities up to Mach 50.
A HyperSoar hypersonic Global Range Recce/Strike Aircraft the size of a B-52 could take off from the US and deliver its payload to any point on the globe - from an altitude and at a speed that would challenge current defensive measures - and return to the US without the need for refueling or forward bases on foreign soil. Equipment and personnel could also be transported.
HyperSoar could fly at approximately 6,700 mph (Mach 10), while carrying roughly twice the payload of subsonic aircraft of the same takeoff weight. As a military aircraft, a HyperSoar bomber the size of an F-22 could take off from the U.S. and deliver its payload from an altitude and at a speed that would defy all current defensive measures. It could then return directly to the continental U.S. without refueling and without the need to land at forward bases on foreign soil.
The HyperSoar concept promises less heat build-up on the airframe than previous hypersonic designs - a challenge that has until now limited the development of hypersonic aircraft. The key to HyperSoar is the skipping motion of its flight along the edge of Earth's atmosphere - much like a rock skipped across water. A HyperSoar aircraft would ascend to approximately 130,000 feet - lofting outside the Earth's atmosphere - then turn off its engines and coast back to the surface of the atmosphere. There, it would again fire its air-breathing engines and skip back into space. The craft would repeat this process until it reached its destination.
Proponents estimate that approximately $140 million would be needed over the next few years to advance several technologies to the point where a $350 million one-third-scale flyable prototype could be built and tested. About $500 million would be needed to develop the technologies needed and build and test a 16-meter-long flyable unmanned prototype. The development cost of full-scaled HyperSoar aircraft is estimated at about the same as spent to develop the Boeing Company's new 777, or nearly $10 billion.
