Even though wheels aren’t essential to the actual aerial part of an airline flight, it’s generally not great when one of the landing gear wheels shoots sparks everywhere and then, um, falls off. in a small Dash 8-300 commuter plane. Nobody was hurt, just so you know.

A passenger named Tom Van-Aken happened to be in a seat with a great view of the landing gear during takeoff, and shot this rather alarming video:

Yeah, that’s not great.

The Dash 8-300 has three landing gear assemblies, each with two wheels, and after circling around for about two hours, the 49-passenger aircraft returned to Montreal to land, which the pilot was able to pull off, sans the missing wheel, without incident.

Yikes, right?
