I've been informed that my memory's once again faulty.

It was the Step 2 Pegasus 3rd stage (1994 29B through whatever) which
exploded in to a cajillion fragements.  There was no problem with the REX
II launch.


I had also said:

Like I said - unless you're really, really good.  The casual person who
just goes outside to view Mir with the naked eye isn't going to be able to
spot this relatively small object.  But best of luck to whoever does try!
