Despite a losing all hydraulic power and therefore all ability to manipulate the flight controls (rudder, elevators, ailerons, flaps) following a midair uncontained failure of the tail-mounted #2 engine, the crew of this DC-10 en route to Chicago from Denver managed to guide the plane to a fiery crash landing at Sioux City airport on July 19, 1989, killing 111 of those aboard. A DC-10 instructor who was a passenger on the flight assisted the crew by delicately varying the thrust on each of the two remaining engines, enabling them to reach the runway and preserve 185 lives.
