==Major incidents==

[[China Airlines Flight 140]] crashed, causing many deaths, due to a misunderstanding about the manual overrides for the [[autopilot]]. The Take-Off/Go Around system had been activated to abort a landing. It was programmed to ignore manual controls in this situation but the human pilots tried to continue the landing. The conflicting control signals from the pilots and autopilot then resulted in the aircraft stalling and crashing. The autopilot for this aircraft type was then reprogrammed so that it would never ignore a manual override.<ref>{{citation |url=http://books.google.com/books?id=SG07muS_S2EC |page=151 |title=Taming HAL: designing interfaces beyond 2001 |author=Asaf Degani}}</ref>

== Examples in fiction ==

As a plot device manual override is often used in [[Sci-Fi]] because of the usual prevalence of advanced / electronic technology. For example:

* In [[Star Trek]] many automatic systems, such as the automatic navigation, or the 'site-to-site transporter' can be overridden. A slightly different type of manual override is used in the film ''[[Star Trek: Insurrection]]'', when acting Captain of the [[Starship Enterprise]] (E) William Riker asks the computer for the 'manual command column', in effect a [[joystick]] which gives him [[pilotage]] control of the ship.

* In ''[[Casino Royale (2006 film)|Casino Royale]]'' (2006), a villan overrides the emergency [[fire sprinkler]]s at [[Miami airport]] and starts a distraction so that he can blow up a plane with a remote-controlled [[pipe bomb]].
