Had an aborted takeoff from YOW (or may have been YEG) many years ago. AC A320, I believe. Captain said a cargo door open indicator came on during the takeoff run. I think fans were brought out to cool the brakes.
Had smoke in cockpit and Business Elite cabin on DL 763 from MAN to JFK in summer 2000. Made emergency landing in Goose Bay.
Had an AC aircraft touch wings with an adjacent AC aircraft pushing back from the gate at YYZ many many years ago.
