This is very interesting and pretty good.
Add the following, which don't kill the idea, but augment it, and
assume the orbiter's OMS capable of kicking it up to the station:
Let's say they figured out on the 17th that something "had to be
done."
1) Indeed, Columbia did not have a robot arm
2) Columbia was carrying two EVA suits. (I'll double check, but I
think that's accurate)
3) The Spacehab RDM module is in Columbia's payload bay, and I am
guessing that it could not be jettisoned - The port entrypoint on
Columbia does not double as an airlock.
The good part is that this plan does *not* involve parking Columbia
on the ISS - no one should want to attach 232,700 pounds of
deadweight to the station. Even if she could make it up the well that
far, she'd bring the station down in a month without fuel to boost.
Additionally, 3 people could have been back already, on the
previously jettisoned Soyuez lifeboat in January, and up to three on
the next one. Typically a shuttle can take three additional
passengers on the second floor deck somehow (never saw the schematic)
Bringing the total to 10.
