A global mistake caused by just 'sloppiness'.

5 POINT: World / Blunder

"5 global mistakes caused by a little 'sloppiness'."

1. The only key that sank the Titanic.

The binocular locker lock key was kept with the officer who had been moved urgently before the ship left, causing the guard on the bird's nest to lose sight of the iceberg at a distance enough to turn dodgy in time.

2. The Mars probe exploded because of the "measurement unit."

NASA lost $125 million worth of the craft simply because two teams of engineers used different units of measurement, one using the metric system but the other using the British system, making orbital calculations so erroneous that the ship crashed into Mars.

3. Safety test that destroyed Chernobyl

The worst nuclear tragedy in history was caused by the decision to shut down the safety system to "test" its operation in critical conditions, which went wrong to cause the reactor to explode in minutes.

4. High-speed rail that is "too wide"

French Railways placed a huge order for new trains, but found that the car itself was wider than the 1,300 station platforms across the country, costing huge extra money to smash and expand all the new platforms.

5. Leaning tower of Pisa caused by soft soil

The architect calculated the foundation was too shallow on a soft layer of soil, causing the bell tower to lean since construction had not yet reached halfway; the mistake of exploring this area later turned out to be a wonder of the world.
