You are watching: What major engineering blunders were results of faulty measurement
The French fiasco has actually been blamed by SNCF top top the national rail operator RFF. Yet sometimes over there is no-one rather to re-superstructure responsibility. Below are 10 instances where a small error has actually proved an extremely expensive, or even fatal.
Designed come orbit Mars together the an initial interplanetary weather satellite, the Mars Orbiter was shed in 1999 due to the fact that the Nasa team supplied metric devices while a contractor offered imperial. The $125m probe came as well close come Mars together it tried come manoeuvre into orbit, and also is thought to have been damaged by the planet's atmosphere. An investigation said the "root cause" that the loss to be the "failed translate into of English units into metric units" in a piece of floor software.
In 1628, crowds in Sweden watched in horror as a brand-new warship, Vasa, sank much less than a mile into her maiden voyage, v the death of 30 world on board. Equipped with 64 bronze cannons, that was thought about by some to be the most an effective warship in the world. Experts who have actually studied it because it was increased in 1961 to speak it is asymmetrical, gift thicker on the harbor side 보다 the starboard side. One reason for this might be that the workmen to be using various systems the measurement. Archaeologists have discovered four rulers supplied by the workmen who built the ship. 2 were calibrated in swedish feet, which had actually 12 inches, when the other two measure Amsterdam feet, which had 11 inches.

In 1983, an air Canada flight ran out of fuel over Gimli, Manitoba. Canada had actually switched come the metric system in 1970, and the airplane is reported to have been wait Canada's an initial aircraft to usage metric measurements. The plane's on-board fuel gauge was not working, so the crew provided measuring "dripsticks" to inspect how much fuel the airplane took on throughout refuelling. Points went wrong as soon as they convert this measure up of volume into one of weight. They got the number right, but the unit wrong - mistaking pounds of fuel for kilograms. Together a result the aircraft was delivering about half as much fuel together they thought. Luckily, the pilot was able to land the plane safely on the Gimli runway, giving the airplane the nickname "Gimli Glider".
