A side panel of an airplane broke off an Alaska Airlines plane mid-flight Friday evening as it headed to Ontario from Portland.
According to the airline, Flight 1282 from Oregon to Southern California experienced an “incident this evening soon after departure.” The plane landed safely back at Portland International Airport despite the issues.
Some of the flight's 174 passengers described a loud 'boom' or 'pop' sound as the panel blew off shortly after takeoff from Portland, where the plane returned for an emergency landing. The blowout was followed by a howling sound of wind streaming into the cabin.
"Everything was going fine, and then we just heard a loud 'bang' or like a 'boom,'" a passenger told NBCLA. "I looked to my left, and there's this huge gaping hole on the left side where the window is. At first I thought it was the emergency door, but there was no door there. It was part of the wall that blew off."
