On July 7 of last year Air Canada Flight 759 from Toronto to San Francisco was cleared to land on runway 28L. It lined up to land on taxiway C instead, which had four planes on it waiting for take off.
The NTSB released security camera footage of the Air Canada Airbus A320 about to touch down on the taxiway.
Watch the upper left hand corner of this video from terminal 2 security to see the plane pull up at the last moment.
The Air Canada jet flew over a United 787 and initiated an aborted landing and go around. United can be heard on air traffic control audio saying “Where’s this guy going? He’s on the taxiway.”
Air Canada descended to as low as 59 feet — just three above the height of a 787. Just after the United widebody was a Philippine Airlines Airbus A340. The captain of that aircraft turned on its landing lights to make itself visible to incoming aircraft.
This narrowly averted incident could have become the worst aviation disaster in history.
