I have been reading about this, especially since my grandson is a pilot and will soon be flying for Alaskan Airlines. This plane had only been in service since November 2023, so it was a recent addition. The door that blew off was not set up to be used, and must not have been fastened on to the plane properly because you can see that the plane itself is not warped or damaged, just the door assembly came off.
It is a good thing that it happened right after the plane left Portland and they had not reached cruising altitude yet, and that no one happened to be sitting in the seat near the door because the seat was pulled out also.
Alaskan Airlines has grounded all of this type of planes, and now the FAA has also ordered all other airlines to ground this plane while they re-inspect them and Boeing finds out why this terrible lapse in quality control happened.
Thankfully, none of these planes will be flying now, at least for some time; but it is a good reason to always keep your seatbelt on.
Probably no one was screaming because they had to grab the air vents and breathe with that, so no time to even scream. They did all seem to handle it really well.
