From: Emil Rainero <emil> 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. Emil Rainero emil@Rochester
