Small bugs can lead to large disasters

Thank goodness most of the computer bugs we face never will never have the disastrous consequences ofthose detailed here. It seems that computer errors (more correctly, human errors in telling the computer what to do) have lead to the explosion of rockets, the disabling of warships, the failure of telephone service, the loss of space exploration vehicles and even the near failure of London's Millennium Bridge.

This site brings home the necessity of heavily testing any computer file you design, whether it is a program, an Excel file with calculations or the simplest database. It seems that the old joke is still true, "To err is human, but to really foul things up requires a computer!"
