[sci.space.shuttle] Replacement for Challenger

johnson@ncrcce.StPaul.NCR.COM (Wayne D. T. Johnson) (10/05/88)

My Brother-in-law works for a large aerospace contractor in Tulsa, he
told me last night that he had visited the shop in their plant where they
were constructing a new set of shuttle cargo bay doors.  For the challenger
replacement.  He also told me that they had already shipped the first pair
and that they had been damaged while unloading in Florida, so now they are
makeing 1.5 sets (a spare just in case).

Are there 2 new shuttles, the challenger replacement AND a shuttle-C (as yet
under planning, as Henry suggests).

This also leads me to the question, if the doors are fairly fragile, could
one be damaged by banging a recovered satalite or shuttle-C engine pod? And
what would be the concequense?

There is no commitment to anything but the Challenger replacement and (I
think) a new set of "structural spares"; I'm not sure whether the latter
includes the doors.  Shuttle-C would not use an orbiter fuselage at all
and hence wouldn't have payload-bay doors.  Various people, notably NRC,
have pointed out that another accident is a distinct possibility and it
would be a mistake to shut the production line down, but not much has been
done about this yet.

It's a risk.  They try to be careful about such things.  Provided it didn't
make too big a hole, the consequences might not be anything very drastic;
the doors are, after all, in a relatively low-temperature area on reentry.
Major maintenance might be needed afterward.
