American Airlines Flight 191
The plane, which just arrived from Phoenix, was assigned to fly Flight 191 from Chicago to Los Angeles. At 2.59pm (local time GMT-6), the plane began its taxi to Runway 32R, and at 3.02pm was cleared to takeoff. However, as First Officer Dillard began to rotate, the number one engine, broke off from its pylon on the left wing. With the remaining length of the runway, stopping the plane would be impossible, so the pilots continued with the takeoff, knowing that two engines are enough to fly a DC-10, but not knowing that the engine had completely separated from the aircraft..
