The 19 Greatest Disaster Due to Software

Errors in the software program is not be underestimated. Impact could be so big, like a rocket explosion, falling stock markets and even create a third world war. Here is a list of the biggest disaster ever caused by software errors:

1. Rocket Mariner I (1962).
This rocket launch out of the path and destroyed.
Penyebabny: programmer forgot to write the code overbar.


2. Satellite Eole I (1971).
France's satellite this fall with 72 weather balloons.
Cause: The request to send the measurement data by the software mistakenly translated as self-destroy command


3. Satellite Nimbus 7 (1978).
Ignores Sateli ozone hole over Antarctica.
Cause: software analysis considers the unusual value as errors in measurement and then correct it.

4. Atomic Reactors (1979).
Five American atomic reactor does not work because the software gives the wrong value for the measurement of earthquake strength.
Cause: The program to calculate the sum which should be the root of the sum of squares.

5. Gas Pipeline (1982 Top Secret).
Siberian gas pipeline exploded due to over-pressure.
The reason: the Soviet Union to buy a control program that has been manipulated by the United States.


6. Third World War (1983).
A Soviet satellite reported an inter-continental rocket five. Colonel Petrow then saw as a threat even though it was wrong.
Cause: software interpret reflected light as an enemy rocket.


7. Therac 25 (1985-1987).
X-ray instrument killing many patients due to excessive doses of light.
Cause: The software can only perform many tasks at once well if the user gives commands slowly.


8. Wallstreet (1987).
Bursa fell causing a daily loss of 22.6% or 500 billion dollars.
Cause: The software market is not fast enough to process order buyers of shares. Resulting in panic in the transaction.


9. USS Vincennes (1988).
U.S. warships are firing an Airbus passenger plane owned by Iran, 290 passengers were killed.
Cause: The system of "Aegis" 400 million dollars worth of Airbus reported it as "assumed hostile". The crew then thought there was an attack aircraft.

10. AT & T (1990).
New phone software force all central swithching into reset mode in the chain. Therefore, the phone can not be used for nine hours.
Cause: incorrect use command "break".

11. Patriot (1991).
Defense weapon system is facing rocket failed Scuds. As a result 28 soldiers were killed.
Cause: conversion error in counting time. Value increases if the system worked longer.


12. Denver Airport (1995).
Baggage system new full-automatic is not working.
Cause: too many complex commands that the software overload.


13. Ariane 5 (1996).
This rocket off course and exploded.
Cause: Overflow while converting a floating value in 64-bit software "Ariane 4".


14. Mars Climate Orbiter (1999).
These explorers of Mars atsmofir burning.
Cause: The instrument measures the power unit of the British pound, while the software NASA uses Newton units.


15. Mars Polar Lander (1999).
Explorers to Mars this fall with a speed of 80 km / h and destroyed.
Cause: define the software to issue commands as the status of the landing foot has landed so turned off the engine.



16. Blackout (2003).
Because the network overload, electricity for 50 million households in the U.S. and Canada extinguished.
Cause: The function of alarm in the power management software does not work.



17. Hartz IV (2004).
Hundreds of thousands of recipients "Hartz IV" does not earn money.
Cause: Software to fill the recipient's account number from the wrong page so filled with zero


18. Airbus A380 (2005).
This giant jet at a cost of 5 billion euros larger and delayed completion.
Cause: the designers of this plane using CAD-software version of CATIA different from each other.



19. BNP Paribas (2009).
The bank's software looted 10 thousand accounts 600,000 customers by making transactions over and over again.
Cause: unknown.
