Numerous people have pointed this out, but nobody has taken issue with the
claim of 6 reentries. I'm aware of only three relevant spacecraft failures,
of which one wasn't a reentry and one "leaked successfully."
Can someone explain what the other three were, or alternatively, reassure me
that I'm not senile?

Apollo 17. I believe that Gene Cernan was the last human to walk on the
surface of the Moon.
Missions were planned through Apollo 21, but funding was cut due to
Vietnam, etc.

_Fallen Angels_ is by Larry Niven, Jerry Pournelle, and Steven Barnes.
Niven and Pournelle have done many many other books together, such as
_Footfall_, _The Mote in God's Eye_, _The Gripping Hand_, etc.
They also formed the Citizens' Advisory Council on National S[ace Policy,
which sold Ronald Reagan on the idea of SDI.
Phoenix is the brainchild of Gary Hudson, who appeared as himself in the
book. He can be reaced on BIX as "ghudson".

I would think that it's probably not possible; not with the materials we have
now, and not on this planet.
The big problem, assuming you already have a power source capable of pushing
a barn door at Mach1, is to keep the nose from caving in. This is already
a problem with the (fairly low) speeds used now. Reinforcing the nose
enough to keep it rigid would probably make the craft far too heavy. Also,
the turbulence experienced in passing the sound barrier would, I think, be
enough to do in any LTA we could build.
I'd still love to see one, though...

I understood it's a contraction of GEMINi GAmma-ray source.
I could be wrong.
