Passenger videos plane wheel disintegrating during takeoff

Imagine settling in for your flight, gazing benignly and vacuously out of the window as the jet taxis and roars into motion, only to notice that one of the wheels is spitting sparks and disintegrating like a firework.

Air Canada Jazz Dash 8-300 #AC8684 to Saguenay lost a wheel as it departed Montreal yesterday. Sparks were seen prior to separation. The flight returned safely to Montreal.
Video shows departure & wheel falling off, passengers being calm and a smooth landing.

Note how incredibly smooth the return landing was.
