Jim, your point is well taken; given the actual situation, i.e., no way
to actually fix damaged tile, an eyeball inspection of the damage may
have led the decision tree down a path that might have included an ISS
rendezvous or an "unusual" re-entry. An EVA to effect a repair is
something that could only have been accommodated through advance
preparation

Jim, if you want to get into a pound^H^H^H^H^Hgram-for-gram argument,
fine. I'll trade you an EVA suit for a couple of weightless-termite
experiments (I'm being facetious, but I think you see my point). More
seriously, how about trading an EVA suit for a crew member? What, you
can't accomplish as much with crews of only six? Well, fine, let's have
three-year "WTF?" sessions every few years when we lose an orbiter and
see if we accomplish more.

I agree; there needs to be some redistribution of effort/money that
reserves manned spaceflight for really, really stupendous feats in
pursuit of Answers to Big Questions. I never cease to be amazed at what
we learn from robotic probes, and I am about ready to see all the "which
way does grass grow in space" experiments left to robot satellites.
I'm ex-DOE, so the abandonment of DOE's SSC after it only succeeded in
the matter/anti-matter annihilation of several billion dollars is to me
an example of the worst this country has to offer (shoddy procurement
practices; my wife and a few others like her probably could have saved
it)
