The plane had a double-engine failure near Winnipeg on the flight to Edmonton, Alberta.
No engine failure. They ran out of jet fuel. The engines were working just fine.
I was a flight mechanic on 767/757 for 5 years. Our indicators were metric, reading kilograms. I also fueled the aircraft. The fuel was delivered in gallons or liters. It was often ordered in pounds. Density was calculated in pounds. Uplift was reported to the crew in kilograms and reported to the company in gallons. It was always done with no time to do it.
