An Alaska Airlines flight from Seattle to San Diego had to make an emergency landing and was forced to return to an airport in Seattle shortly after departure on Monday when an engine cover detached, according to the airlines. The airlines reported an unusual vibration on the left side of the aircraft after departing. The plane returned to the airport and landed safely. CBS 8 spoke to Jacqueline Stonas, a passenger onboard that flight. She was seated toward the back of the plane and didn't see the metal fly off. She said the video circulating on social media was shot as the plane was making the emergency landing in Seattle.
