What an amazing thing to hapen.  NASA must be wondering if they did the right
thing replacing the original #1 engine.  The original #1 engine was replaced
by an engine from Challenger (flown twice before) due to heat shield 
delamination.  The shield is .0040-in. thich and had delaminated .0020-in.
The other two engines were both veterans of space, #2 having lifted
Spacelab 1 on Columbia and #1 on three flights in Challenger.
Still the engines are are marvel compared to the beasts used on the Saturn 5.
