French Trains Are Too Wide For Tracks
French railway operator SNCF managed to lose around $60 million after they made a very costly error when they designed a series of new trains.

One of the calculations had been carried out in the wrong unit of measurement and the probe flew too close to Mars and crashed on its surface.
