Hey guys; this is no biggie. Just another airframe malfunction issue from Boeing. Happens all the time. Nothing to worry about. I’m sure everything is totally sorted inside of Boeing right now.
A quick Google doesn’t reveal the same issues occurring with any other manufacturers but I sit to be corrected.
I wonder - and this is purely a hypothetical thought - was the door partially armed inadvertently by some passenger fiddling that was never noticed by the crew and allowed the mechanism to be partially primed for an inadvertent deployment due to constant turbulence/vibrations over time?
