When things do not go as
expected…
Selected Major Disasters because of
Software Bug

Mariner Bugs Out (1962)
• Cost
– $18,500,000
• Disaster
– Mariner 1 rocket with a space probe
headed for Venus diverted from its
intended flight
– Mission Control destroyed the rocket
293 seconds after liftoff
• Cause
– A programmer incorrectly transcribed
a formula into software
– The software interpreted normal
variations of velocity as anomalies
– It issued faulty correction commands
that sent the rocket off course

Hartford Coliseum Collapse (1978)
• Cost
– $90,000,000
• Disaster
– Steel-latticed roof collapsed
under the weight of wet snow
• Cause
– CAD software was used to design
the coliseum
– A programmer incorrectly
assumed the steel roof supports
would only face pure
compression
– One of the supports unexpectedly
buckled from the snow
– This set off a chain reaction

Patriot Fails (1991)
• Cost
– 28 soldiers dead
– 100 soldiers injured
• Disaster
– During the first Gulf War, a Patriot
Missile system in Saudi Arabia failed to
intercept an incoming Iraqi Scud missile
– The missile destroyed a U.S. Army
barracks
• Cause
– A software rounding error incorrectly
calculated the time
– This caused the Patriot system to react
too late to the incoming Scud missile

Mars Climate Crasher (1998)
• Cost
– $125 million
• Disaster
– After a 286-day journey from Earth, the
Mars Climate Orbiter fired its engines
to push into orbit around Mars.
– The engines fired, but the spacecraft
fell too far into the planet’s
atmosphere, likely causing it to crash
on Mars.
• Cause
– The software that controlled the
Orbiter thrusters used imperial units
(pounds of force), rather than metric
units (Newtons) as specified by NASA.
