*[[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 pushing the control column fully forward. This caused the plane to lose speed 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, together with the cabin crew moving the passengers forward to alter the center of gravity. 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]], making it the deadliest aviation accident in U.S. history.
*[[Japan Air Lines Flight 123]], a [[Boeing 747]], on 12 August 1985. A faulty repair years earlier had weakened the aircraft's rear pressure bulkhead, which failed in flight. The [[vertical stabilizer]] and much of the aircraft's [[empennage]] was blown off during the decompression. The decompression also ruptured all four hydraulic lines which controlled the aircraft's mechanical flight controls. The pilots were able to continue flying the aircraft with very limited control, but after 32 minutes the aircraft crashed into a mountain, killing 520 of the 524 people aboard in the deadliest single aircraft disaster in history.<ref>Gero 1997, p. 189.</ref>
