The National Post reports in its Wednesday edition that an Air Canada Airbus A-330 travelling from Montreal to London lost a wheel during takeoff on Sunday night and still managed to arrive safely in what one airport worker called a "miracle" landing. The Post's Caitrin Pilkington writes that Flight AC-864 took off at 7:45 p.m. with 294 passengers on board. No irregularities were noted at the time. However, when the plane landed in London at 7:25 a.m., the aircraft sustained serious damage to the landing gear because of the absence of the wheel. The plane was expected to fly back to Montreal the following day, but is being held back for repairs. It was a landing that could have been fatal. "I've never seen anything like this in my life," according to an airport worker who spoke to The Sun. The pilot had not noticed the wheel bearing collapsing and was horrified to learn of the damage only after the plane had landed, the newspaper reported. It is customary for pilots to perform a safety check before a flight. The reason the malfunction was not spotted before takeoff is unknown. Whatever happened to the wheel that fell out of the sky? On Monday, it was found stuck in a fence a few kilometres from PET airport.
