As far as the engines flipping over the wing, if the engine is swinging below the wing, isn't there a chance the engine may swing back up into the wing before the rear bolts detach? Incidentally, back to the AA DC-10 crash in Chicago, when the enghine detached, I remember hearing that the engine went above the wing and sliced through the wing's upper skin, cutting all of the redundant hydralics to the elevators. The elevators retracted which resulted in the uncontrolled roll. Also, as far as the AA 727 that loss an engine over NM; it wasn't just any old FOD, it was blue ice from a improperly secured laboratory holding tank door, which is located ahead of the intakes. The aircraft landed in Tucson while I was living there; I remeber the passengers saying that the plane shook somewhat violently and then stopped shaking. The crew had no idea that the engine had torn completely loose. Finally, I know I have seen aircraft fly with one thrust reverser deployed (although I assume with engine thrust cut back); its part of the aircraft certification process so an accidental reverser deployment need not be fatal. Anyway, some musings. Bruce L. OPinions are mine, and not those of PNL, Battelle, or anyone else."
