Close Call At SFO

100 feet:

SAN FRANCISCO — 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.

“If it is true, what happened probably came close to the greatest aviation disaster in history,” said retired United Airlines Capt. Ross Aimer, CEO of Aero Consulting Experts. He said he’s been contacted by pilots from across the country about the incident.

“If you could imagine an Airbus colliding with four passenger aircraft wide bodies, full of fuel and passengers, then you can imagine how horrific this could have been,” he said.
