It could be one of the main two flight 191's: American Airlines Flight 191 was a DC-10 leaving O'Hare, worst aviation incident in US history: http://en.wikipedia.org/wiki/American_Airlines_Flight_191 Delta Airlines Flight 191 was a L-1011 leaving Ft. Lauderdale, not as bad as AA 191, still horrible: http://en.wikipedia.org/wiki/Delta_Air_Lines_Flight_191 Those are the two most famous flight 191's, there are a few others including: Comair (Delta) Flight 191 from Lexington: http://en.wikipedia.org/wiki/Comair_Flight_191 Prinair Flight 191 from San Juan: http://en.wikipedia.org/wiki/Prinair_Flight_191 X-15 test flight over Delmar: http://en.wikipedia.org/wiki/X-15_Flight_191 My guess is it's the first one, the most famous one, the AA DC-10.
