Thankfully we seem to have standardized on plug type doors, not outward opening ones, since the dc10 disaster. I wonder what happened.

Considering emergency exit doors, cargo doors and primary boarding doors are all plug design it must have been a serious failure.

This is pure ignorance on my part, but do plug type doors seal as strongly when on the ground ?

>it could be something totally innocuous that caused the door to come off If making the door come off doesn't make the cause by definition not innocuous, then what are their standards for what is and isn't innocuous?

In this context, innocuous might mean something that would not have any meaningful chance of occurring in real-world operation, and should not have occurred during the stress test. So purely an artifact of the test, in other words.

One would presume this is purely a function of the pressure differential between the cabin and environment, which they presumably controlled for.
