    Scramjets, short for supersonic combustion ramjets, will hopefully
    be able to launch satellites more cheaply or take passengers from
    London to Sydney in about two hours. The test engines need a
    rocket boost as they will not ignite until reaching a speed of
    Mach 5 or five times the speed of light. The engine sucks oxygen
    from the atmosphere to burn its hyrdrogen fuel. Scramjet engines
    are expected to be ready for commercial use in about 10 years.

Andromeda, here we come!  Or...  Talk about a kinetic weapon!

Five times the speed of LIGHT???
