American Airlines Flight 191

Also known as AA191, AAL191, AMERICAN 191

American Airlines Flight 191 was a regularly scheduled domestic passenger flight from O'Hare International Airport in Chicago to Los Angeles International Airport. On the afternoon of May 25, 1979, the McDonnell Douglas DC-10 operating this flight was taking off from then-existing runway 32R at O'Hare International when its left engine detached from the wing, causing a loss of control. The aircraft crashed about 4,600 feet (1,400 m) from the end of runway 32R. All 271 occupants on board were killed on impact, along with two people on the ground. With a total of 273 fatalities, the disaster is the deadliest aviation accident to have occurred in the United States.
