The Incident of Air Canada Flight 143
On July 23, 1983, a remarkable aviation incident occurred when Air Canada Flight 143, known as the Gimli Glider, ran out of fuel mid-flight. The flight, which was en route from Montreal to Edmonton, faced a dire situation when the pilots realized that they could not reach their destination due to fuel miscalculations. What followed was a demonstration of excellent airmanship as the crew prepared for an emergency landing.
What Caused the Incident?
The event was precipitated by a critical mistake in the way the fuel was measured. In the early 1980s, Air Canada had switched from imperial to metric for fuel measurements, which caused confusion among ground crew and flight personnel. During refueling, the flight was mistakenly filled with metric liters when the crew intended to fill it in imperial gallons. This error significantly reduced the amount of fuel on board without the crew’s realization.
The Crew's Response
Pilots Captain Robert Pearson and First Officer Maurice Quintal swiftly reacted to the emergency once they discovered that the fuel gauges were showing empty. They had to execute what is known as a deadstick landing, as the aircraft's engines had lost power. With the nearest airport far beyond their current position, they set their sights on a decommissioned airstrip at Gimli, Manitoba.
The Miraculous Landing at Gimli
The successful landing of the Gimli Glider is hailed as one of the most incredible feats in aviation history. Despite having no engine power, Captain Pearson managed to glide the Boeing 767 for several miles before coming in for a landing. When they reached Gimli's runway, it had recently been converted to a temporary race track, meaning that the runway was populated by spectators and vehicles.
The Landing Process
During the approach, the crew used their remaining altitude strategically, relying on their training and intuition. Captain Pearson expertly lined up the aircraft with the runway, avoiding the obstacles on what was ostensibly a makeshift track. Ultimately, the plane landed smoothly on the runway, with no injuries among the 69 passengers onboard.
The Aftermath of the Incident
The Gimli Glider incident led to an extensive investigation and significant changes in aviation regulations and procedures regarding fuel calculations. It underlined the importance of proper training and communication in the aviation industry to prevent future occurrences of similar mistakes.

The Legacy of the Gimli Glider
Interestingly, after the incident, the Gimli Glider became a beloved part of Canadian aviation lore. The plane continued to operate for many years after the incident and became a symbol of ingenuity and quick thinking, turning a potential tragedy into a celebrated success story.
