It's a sight you don't want to see from your window seat.
Video taken by a passenger on a flight from Montreal appears to show the one of the wheels of his plane spark, burn and then detach from the plane.
The incident happened on an Air Canada Jazz flight AC8684, as it took off for Saguenay Quebec.
Passengers aboard the De Havilland Canada Dash 8-300 propeller plane watched on in horror as the wheel detached and fell away from the plane.
One passenger who was calm enough to film the event, later posted the footage to Twitter with the caption: "Well, now I'm on an aeroplane that just lost a wheel … 2020 starts pretty well."
