WJMan, perhaps yuo can explain this--since you seem to be so up on the goings ons:
3 weeks ago in YEG. Fueling company suspends ops temporarily due to unfit fuel. AC , Jetsgo and WJ at the gates and told they have to de-fuel. AC and Jetsgo are stuck for 5 hours because to de-fuel completely (ie. get rid of even risidual fuel in the low points) requires maintenance and a long time draining.
Yet WJ pushes an hour later!!?? They simply refueled, left the 'unuseable' at the bottom of the tanks and took off.
Ahh... there's the rub.
