*[[Turkish Airlines Flight 981]], a [[McDonnell Douglas DC-10]], on 3 March 1974. Similar to American Airlines Flight 96, the flight experienced an [[explosive decompression]], when flying over the town of [[Meaux]], France, caused by a rear cargo door failure. The rear main cabin floor collapsed and severed all flight controls. While the plane went into a vertical dive, the captain called for "Speed!", meaning increasing engine thrust to push the plane's nose up. The plane began to level out, but had lost too much altitude and slammed into the [[Ermenonville Forest]]. All 346 people on board were killed upon impact, and it became the worst single aircraft disaster without survivors, and the fourth deadliest [[List of accidents and disasters by death toll#Aviation|aviation death count]] ever.<ref>"Accident Details".

*[[Delta Air Lines Flight 1080]], a [[Lockheed L-1011 Tristar]], on April 12, 1977, suffered a structural failure of a bearing assembly controlling the aircraft's left stabilizer, which caused it to jam in a full trailing edge up configuration. The plane pitched abruptly upwards and the pilots could not counteract the pitching force even when pressingpushing the control column fully downforward. This caused the plane to lose speed rapidly and nearly stall. The pilot managed to regain control by using the Tristar's tail engine at maximum power and lowering the thrust on the wing engines in order to generate differential thrust. The airliner landed at [[Los Angeles International Airport]], with all 41 passengers and 11 crew being unharmed.<ref>{{Cite news|url=https://www.washingtonpost.com/archive/opinions/1978/10/08/the-saving-of-flight-1080/bc18f021-691d-4b19-8041-dc03a089bf6d/|title=The Saving Of Flight 1080|date=1978-10-08|newspaper=Washington Post|access-date=2018-05-19|language=en-US|issn=0190-8286}}</ref>

*[[American Airlines Flight 191]], a [[McDonnell Douglas DC-10]], on 25 May 1979. The failure of the #1 engine mounting pylon and subsequent separation of the engine from the aircraft resulted in severed hydraulic lines and electrical system damage. The left wing [[Leading-edge slat|slats]] retracted due to the loss of hydraulic pressure and aerodynamic forces, while the right wing slats remained extended. The damaged electrical system prevented the slat retract indicators and [[stick-shaker]] on the [[yoke]] from functioning, so the crew was not alerted to the slat retraction nor impending stall. All 271 on board were killed, as well as two on the ground at [[O'Hare International Airport]] in [[Chicago]], [[Illinois]].
