Jason,
The Germans built a rocket-launched fighter in WW2 (the ME 163?). After the
fuel was exhausted, it would glide back to the airfield. The hypergolic fuel
used made the glider more dangerous to the ground crews than it was to the
Allies.

Space Shuttle. BTW, does (or did) the Space Shuttle have an airworthiness
certificate?

Someone here in the US I think is working on a scaled version of the 163, but
using a safer fuel I trust.
