Now if they were out of hours and had the passengers been informed they might have got away with it. And as a plan that might have worked. Even if a "guessed" fuel load was uplifted at least the lights would not have gone out. But someone, somewhere forgot to think about the about all the practicalities of looking after a plane load of passengers for a several hours. Things like water, toilet service, food, drink etc. have to be considered. Having little other information other than Ottawa airport saying they could have helped and a passenger dialling 911 all we really know is that this was an almighty cock-up.
