On Tuesday, Boeing’s president and chief executive Dave Calhoun said the firm was “acknowledging our mistake”.
The door “plug” which fell away from the aircraft weighed 27kg (60lb) and was used to fill an emergency exit that was built into the plane, but not required by Alaska Airlines.
The missing section of the plane was retrieved from the back garden of a Portland teacher, according to the US National Transportation Safety Board (NTSB).
Speaking to Boeing staff, Mr Calhoun said: “We’re going to approach this number one acknowledging our mistake. We’re going to approach it with 100% and complete transparency every step of the way.”
Mr Calhoun reassured staff that Boeing would work with the NTSB to investigate the cause of the accident.

Pretty sure they already know…

"United Airlines said Monday that it has found loose bolts during inspections of its 737 Max 9 fleet in the wake of a door plug getting blown out of an Alaska Airlines plane over the weekend.
Monday evening Alaska Airlines said initial inspections of its 737 MAX 9 fleet revealed “some loose hardware” visible on some aircraft."
That’s the direct cause of the accident, but there’s still the question of how the bolts came loose in the first place. It could be a quality control issue which is relatively easy to rectify, or it could be a design issue with the plane leading to excessive vibrations loosening them, which is a MUCH bigger issue.
Boing: “Ah, put some Loc-Tite on it, it will be fine…” Probably.
