On January 5, 2024, 171 passengers and six crew members boarded Alaska Airlines Flight 1282 in Portland, Oregon, for what they believed would be a short, uneventful trip to Ontario, California. However, just ten minutes after take-off, they heard a loud explosion. Before anyone could react, an aircraft panel broke off and flew away, leaving behind a gaping hole. It was later revealed that the panel was a "door plug." It covers optional emergency exits in some Boeing 737-9 Max airplanes.
