@amazeifystore: The numbers matched. The units didn’t. ✈️ In 1983, a fuel conversion error left Air Canada Flight 143 with about half the fuel needed. When both engines quit at 41,000 feet, Captain Bob Pearson glided the 767 to an old airfield in Gimli. Could you have spotted the mistake? #GimliGlider #AviationHistory #Engineering #UnitConversion #AirSafety #Flight143 #AviationFacts
