re: Alaskan Airlines plane had an issue tonight as part of the plane fell apart in the air

There is so much terrible information in this thread it's hilarious.

Plane is a Boeing 737 MAX-9
The door is a plugged emergency exit door that is not in use on most configurations and only used on high density aircraft
The FAA has grounded all 737 MAX-9s until inspections have been completed.
Alaska and United, the only two US operators of the 737 MAX-9 have completed inspections on some aircraft and they have returned to regular service.
This is the same plug door that has been flying on the 737-900 for years with no issues.
