Near disaster at San Francisco airport

An Air Canada plane preparing to land in San Francisco almost smashed into four planes on the ground when the pilot mistakenly aimed for the parallel taxiway rather than the runway itself.

In what one aviation expert called a near-miss of what could have been the largest aviation disaster ever, an Air Canada pilot on Friday narrowly avoided a tragic mistake: landing on the San Francisco International Airport taxiway instead of the runway.

Sitting on Taxiway C shortly before midnight were four airplanes full of passengers and fuel awaiting permission to take off, according to the Federal Aviation Administration, which is investigating the “rare” incident. An air traffic controller sent the descending Air Canada Airbus 320 on a “go-around” — an unusual event where pilots must pull up and circle around to try again — before the safe landing, according to the federal agency.

FAA investigators are still trying to determine how close the Air Canada aircraft came to landing and potentially crashing into the four aircraft below, but the apparent pilot error already has the aviation industry buzzing.

This would have been the ultimate in pilot error, and might end the career of that pilot.
