Southwest Airlines planes clip wings at Oakland International Airport

OAKLAND, Calif. (KABC) -- Southwest Airlines has launched an internal investigation after a plane's wingtip was damaged after it clipped another plane's wing at Oakland International Airport.

A photo was taken by a passenger on board Flight 2674 to John Wayne Airport in Orange County Sunday night.

The plane was being pushed back from the gate when the two Boeing 737s came into contact with one another. There were no passengers on the other plane that had arrived from Boise, Idaho earlier Sunday evening.

Passenger Manas Gowd said he felt a jolt.

"You could tell that both planes had clipped each other because the movement wasn't natural," he said.

Southwest Airlines said there were no injuries reported to the passengers or crew. Both planes were taken out of service to undergo maintenance checks.

The flight was canceled and passengers were rebooked onto other departures scheduled for Monday.

"Safety is always our number one focus and we are conducting an internal review to identify details surrounding yesterday's event," the airline said in a statement.

In June, two Southwest Airlines planes clipped wings at Bob Hope Airport in Burbank. None of the passengers on board the Southwest Airlines flights were injured.
