An Air Canada plan landed in London without a wheel after the tyre snapped off in mid air.
The incident happened shortly after take-off on the Montreal to Heathrow flight yesterday, according to Daily Mail.
But the pilot only realised after being told by airport workers in Britain after landing safely, without any difficulties.
Damage to the Boeing 777-300's suspension was also reported after landing at Heathrow.
The missing wheel was later found rooted in a fence just a few miles from Pierre Elliott Trudeau Airport in Montreal.
