Metal peels off Alaska Airline plane, lands safely

A passenger of an Alaska Airline plane flying to San Diego from SEATAC snapped a photo of what appears to be metal peeling off of the wing of the plane. Thankfully, the plane landed safely.

An Alaska Airlines flight headed for San Diego returned to Seattle-Tacoma International Airport shortly after takeoff because of an "unusual vibration" coming from the left side of the plane.

A spokesperson for Alaska told FOX 13 News that Flight 558 returned to the airport and landed safely Monday morning. There were 176 customers and six crew members onboard.

The aircraft, a 3-year-old Boeing 737-900ER, was taken out of service while Alaska's safety team investigates.

Customers were rebooked on another flight for San Diego which was scheduled to arrive about 90 minutes late.
