Hmmm. IIRC, there was a major plane crash in Chicago circa 1979 that was also a DC-10 where the left engine fell off.
That one was blamed on faulty maintenance as the AA people tried to take a short cut with engine removal and replacement.
American Airlines 191. Saw the smoke from west suburban Berwyn about 15 miles from crash site. I saw 15 y/o and not a clue about the tragedy that just happened.
