Hypersonic Flight

Hypersonic flight is flight through the atmosphere at speeds above about Mach 5.5, a speed where disassociation of air begins to become significant and high heat loads exist.

Hypersonic flight has been achieved by the Space Shuttle's orbiter, the Apollo command module, Buran and scramjets.
