The Boeing 737 MAX 9 was temporarily grounded – and tremendous faith was lost in Boeing – after a the left mid exit door plug detached from Alaska Airlines aircraft N704AL while performing flight 1282 from Portland, Oregon to Ontario, California.
The NTSB has now issued a report on what happened, and it tracks what readers of View From The Wing already know: the plane left the factory missing bolts to hold the door plug on, and tracking of defects at Boeing seems to be a problem.
