What major engineering blunders were result of faulty measurements?

Answer 1

• The Great Kersten Blunder. (Kersten was the programer that made the error). The Vigor space probe was sent towards Venus, but because of a computer programing error installed on it, a convertion from millimeters to inches was incorrect. It divided by 24.5 instead of 25.4. This error caused it to miss Venus completely and was sent hurling into space. Over 2 billion dollars of technology was lost because of one simple error.
• The Mars Climate Orbiter had a problem when trajectory programming teams from Europe and USA were working in two different measurement systems, imperial and metric. It missed the planet completely and was lost.
• Not exactly engineering but it was an aviation blunder. An Air Canada flight was fuelled in Toronto using pounds instead of liters of fuel. The pilot calculated how much he needed thinking he was getting his fuel in liters and eventually ran out of fuel near Winnipeg. He successfully landed the plane safely at a semi-abandoned WW2 airstrip at Gimli Manitoba.
• The Hubble Space Telescope or HST originally had an incorredtly ground mirror (Link below.)

Answer 2

some major engineering blunders that were results of faulty measurements were that people had the wrong information,didnt know if it was right or wrong.

Answer 3

the iffel tower is 6 inches shorter all because the construction bulider read the measurments wrong

Answer 4

NASA lost 600billion dollars because they measured in chodes
