It was July 23rd, 1983.A Boeing 767 sat in the sky at 41,000 ft. Fresh from the factory. Brand new shiny metal. And dead in the water.
The engines quit.
Both of them.
Forty-three years ago Air Canada flight 143 became a very large paperweight. Sixty-nine souls on board watched their state-of-the-art jet turn into a glider.
Why?
Canada was switching to the metric system.The plane was new enough to use kilograms.The people filling its tanks thought in pounds.
Somewhere the math broke.
Here is what happened. In Montreal 7682 litres of fuel were pumped into the wing. The plan called for 22300 kg. A later add of roughly 5000 litres was added when the calculation was redone. It should have been 20000.
The crew thought they were full.
They weren’t. They were flying on half the fuel.
The gauges were broken.So they measured it by hand. Dipped sticks into the tank. Converted volume to weight. And somewhere along that chain 177 was used as a factor for pounds but treated like kilograms.
“Everyone involved thought the airplane had what it Needed.”
Over northern Ontario the lights came on.
Low fuel pressure.First one engine coughed out. The pilot turned toward Winnipeg.Hoping for help.Hoping the system glitch was fixed by a restart.
The second engine followed.
Silence.
Not the quiet of a library. The silence of a 180 ton aircraft losing the fight against gravity.
The Ram Air Turbine popped out like an orange flower giving back a sliver of hydraulic power. Enough to move the yoke. Not enough to stay airborne.
Captain Robert Pearson had a secret weapon.No airline pilot is expected to carry this one in his resume.
He flew gliders.
His co-pilot Maurice Quintal spotted an old Royal Canadian Air force base at Gimli Manitoba. Pearson aimed the dying bird at it.
They didn’t know one critical thing.
The base wasn’t a base anymore.
One of the runways? A public drag strip.
Cars. Spectators. Kids running around.It was a summer day in a town that expected fast cars not falling airplanes. And because there were no engines running the 767 descended in near total silence.
No roar. No warning.
Just a massive shadow appearing from the clouds.
They were high and fast.Too fast to stop.Too high to land.
Pearson did the unthinkable.He slipped the airplane.Crossed the controls.Dragged the fuselage sideways into the wind. It was a risky glider maneuver in a widebody jetliner.
It worked.
The wheels touched down hard.The nose gear didn’t lock.The plane skidded. Metal tore through concrete. Sparks showered over a confused crowd of spectators.Tires burst into flame.
It slid to a stop before hitting the people.
Every single person survived.The plane stopped.
It became famous.
They called it the Gimli Glider. A name it didn’t ask for.But earned.
It was repaired.
Went back into service.Flew for another 25 years.Carrying people to holidays and business meetings and vacations.
Sometimes a mistake doesn’t end in fire.
Sometimes it just ends with a scrape and a very long story.
You ever notice how bad luck usually wears a label?
“It ran out of fuel because we used the wrong conversion factor.”
