What alternative launch technologies are you thinking about anyway? I am well aware of the different types of engines being developed, (and cancelled willy-nilly by underfunding), and of different fuels being investigated. It is also possible that orbital velocities may be possible with SCRAM jets, (although I do not believe they are in any way safer than rocket engines - rockets have been around for centuries, despite a few cautious claims, I don't think anyone can say for sure their SCRAM worked! The Aussie machine looked interesting - just before it crashed.)
still in it's child phase, But so are rockets, Sure rockets have been
around for a while but they where only used to blow up things,
not carrying people in, Rocket's aren't that safe.
