FirstStep:
On a side note, I do remember seeing a picture of an American 757? that during a ground run up, an uncontained engine failure in #1 resulted in a "chunk" of that engine passing through the fuselage, and damaging the #2 engine. I could only imagine what would have ensued had the event happened at V1.
It was a 767-200. That was about the scariest scenario I've ever seen. In fact, a chunk of disk penetrated (and was stuck in) the #2 core exhaust nozzle, not damaging the engine proper, and I believe #2 would have kept running OK.
But given a slightly different trajectory, disk fragments could easily have penetrated the pax cabin, such as happened to an MD-80 on takeoff (Pensacola?)
