"NTSB Finds Door Plug from Alaska Airlines 1282 Before Mid-Air Blowout"

Alaska Airlines placed restrictions on a Boeing 737 Max 9 after pressurization warnings in the days before a dramatic mid-air blowout, with the missing section of the plane found in a Portland teacher's backyard. The plane, which made a safe emergency landing, had been prevented from making long-haul flights over water due to the warnings. The NTSB reported that the force of the blowout caused the cockpit door to open, and a laminated checklist and headset to fly into the cabin. The FAA has grounded 171 planes of the same type for safety checks, impacting operations for several airlines.
