An investigation is underway after an Air Canada plane nearly landed on a crowded taxiway at San Francisco International Airport on Friday night.
Authorities say Air Canada Flight 759 from Toronto was cleared to land on Runway 28R, but instead the pilot prepared to land on Taxiway C, which had four aircraft on it.
According to audio obtained by CNN, an air traffic controller noticed that the airplane was about to land in the wrong lane and ordered the pilot to "go around" and make another attempt at landing.
"Where is this guy going? He's on the taxiway," the air traffic controller said on the audio.
On the second approach, the pilots landed the plane without incident.
A spokesman for Air Canada said the company is investigating the incident.
A spokesman for the airport said there would be no further comment.
"We are aware of this incident and are in close contact with the FAA on this," San Francisco International Airport spokesman Doug Yakel told CNN.
