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.

Famous quotes containing the word flight:

    “Here I am.... You get the parts of me you like and also the parts that make you uncomfortable. You have to understand that other people’s comfort is no longer my job. I am no longer a flight attendant.”
    —Patricia Ireland (b. 1935)
