That appears to contradict the Komo News report (on which the Seattle Times article is based):
A door blew off a Boeing 777X as the new plane was undergoing what was supposed to be its final structural inspection by federal regulators.
The test is meant to push the plane beyond its limits. Engineers had the plane pressurized and on the ground. They loaded it up well beyond capacity and bent its wings in an extreme manner, in a way almost certain to never happen in the real world.
As the ground test was underway and as engineers and FAA inspectors watched, a door blew off the plane.
Door blows off Boeing 777X during stress test
It's hard to imagine a bunch of FAA inspectors watching just a simple pressurisation test. What's your source for the alternative account ?
