* Probably the worst known roller coaster incident in history occurred on rhe Battersea Funfair Big Dipper on 30 May 1972. The lift chain malfunctioned, followed by the anti-rollback mechanism, and the train rolled back to the station and collided with the other train. Five children died and another 13 were injured. The park struggled on for another 16 months, before closing at the end of the 1974 season.

* [[http://en.wikipedia.org/wiki/RMS_Titanic The sinking]] of the ''Titanic'' on 15 April 1912 was so unexpected because of its novel failsafe design, with multiple watertight compartments that should have been able to keep it afloat even if one compartment was breached. The bulkheads that were supposed to seal off the compartments, while extending above the waterline, were not sealed at the top, meaning that they could still overflow and fill other compartments, something of a design flaw. And of course, the final failsafe on any ship--the lifeboats--failed to save most of the passengers, because there weren't enough of them. The ''Titanic'' had room to carry enough lifeboats, but it sailed with only one-third of its capacity. Contrary to urban legend, this wasn't due to the hubris of the designer and crew in believing it unsinkable. Carrying only a fraction of lifeboat capacity was standard practice at the time, based on assumptions about how slowly passenger ships sank--it was expected that help would arrive before the ship had to be completely evacuated and the lifeboats would simply ferry the passengers to the rescue vessels. The only ships that sailed with enough lifeboats for everybody were warships, which were expected to go down in conditions where they would sink ''fast''. There ''were'' regulations on the bare-minimum number of lifeboats to be carried, but they were based around the weight of the ship, not passenger capacity, and the number aboard ''Titanic'' as-built was already ''over'' that limit.

* In ''Film/StarTrekBeyond'', the air processing system on starbase Yorktown has all kinds of elaborate safeguards to prevent anyone from tampering with it via the computer network. But a person can simply take an elevator to the roof of the building it's on and release a bio-weapon with ease even as people in the command center struggle to overcome those very security protocols to try to stop them.

What's a failsafe? Well, the world is full of a lot of dangerous machinery and devices. Huge electrical turbines and nuclear reactors, Power lines carrying enough juice to light a whole city and pipelines carrying megatons of explosive petroleum or natural gas. Trains speeding down the tracks at 300 km/h, semi trucks that weigh in excess of 40 tons rolling down the freeways, aircraft that weigh more than ''400'' tons flying over our heads. And that's just the stuff that ''isn't'' designed to kill anyone. There's plenty of stockpiled bombs, missiles and such out there too. These could all cause some spectacular collateral damage if they suddenly went out of control.

** The [[Literature/RedDwarf novelisations]] have the accident unfold slightly differently, and notably it ''isn't'' Rimmer's fault.[[note]]Presumably the rather DarkerAndEdgier novel continuity would have made it hard to HandWave Rimmer's [[VirtualGhost personality disk]] not getting ThrownOutTheAirlock by Lister when he found out.[[/note]] Three important warning lights fail to activate, and when several more come on later the engineering watch-stander [[ItsProbablyNothing blames them on the coffee he just spilled all over his keyboard]].
