A series of images has emerged showing the metal paneling covering the engine of an Alaska Airlines plane breaking away from the aircraft during a flight that was forced to return to Seattle.
The plane, which was traveling to San Diego, was forced to turn back around Monday due to an "unusual vibration" on the left side of the aircraft shortly following departure.
An image taken after the plane landed safely showed one of the plane’s engines exposed after the paneling covering it became peeled off.

"The initial big piece ripped off and wrapped around the wing until we landed," Greg Anderson, a passenger who took the photos, wrote on Twitter.
