On 23 July 1983, Air Canada Flight 143 ran out of fuel at 41,000 feet (12,000m) altitude, about halfway through its flight from Montreal to Edmonton. The crew was able to glide the aircraft safely to an emergency landing at Gimli Industrial Park Airport, a former airbase at Gimli, Manitoba.

A math error in converting between metric and non-metric units caused the plane to be loaded with insufficient fuel prior to flight.

Type of aircraft: Boeing 767-200.
Cause of disaster: Fuel starvation resulting from ground and flight crew errors.
