A concept which has been kicking around for a few years, Sanger would use turboramjet engines to propel a winged first stage to Mach 5, at which point a LOX/LH2 propelled second stage -- either an unmanned expendable cargo rocket (like Pegasus) or a reusable winged manned vehicle -- would be released to ascend to orbit. This seems like a better idea than HOTOL or NASP: no need to take the entire vehicle to orbit or to make the first stage capable of flight at extreme hypersonic speeds. Paul F.
