"NTSB Locates Missing Alaska Airlines Door Plug, Prompting Boeing Scrutiny"

The door plug that blew out of an Alaska Airlines flight over Portland has been found in a backyard, as investigations reveal the plane's auto-pressurization fail light had illuminated on three previous flights. The incident caused extensive damage and injuries, prompting the grounding of 171 Boeing 737-9 Max planes for inspection.
