This is the moment a wheel fell off of a Boeing aircraft mid-take off.

Video shows a United Airlines flight taking off from San Francisco International Airport and losing a wheel shortly after.

The wheel can be seen hurtling towards the ground as the plane flies off without it.

The Boeing 777-200 was headed to Osaka, Japan, on Thursday, March 7 but was forced to make an emergency landing at Los Angeles International Airport.

There were no reports of injuries.
