I am presuming that NASA would attempt to autoland a damaged Shuttle
rather than ditching it in the ocean (assuming that an automatic
system to lower the nose gear is in place).

Also, concerning Shuttle consumables, isn't there a system in
development to allow Shuttle to receive power from ISS?

Lastly, why couldn't a damaged Shuttle move to PMA-2 at Node 1 to
allow a 2nd Shuttle to dock with PMA-3 at the Lab?
