#14"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."
"Dr. Curtis said this is not the time to race to conclusions, and it could be something totally innocuous that caused the door to come off. But it could cause delays. "It's unlikely this will speed up certification," he said. "It's more likely it will make the certification team, whoever's involved with Boeing and the FAA, do extra work to figure out what happened."

#16It's a stress test. You would expect things to break during a stress test.

Here is another video of a 777 wing test where it broke at 154% of the [s/normal/maximum theoretical/] load - a bit beyond what was expected by the engineering team. https://www.youtube.com/watch?v=Ai2HmvAXcU0

#18I like how their PR person says "Safety is the highest priority at Boeing."
I feel like the reality is that "doing what our customers tell us so we sell more airplanes than Airbus" is their actual highest priority. I wonder how they fix that. I wonder if it's even possible for a publicly-traded corporation to do?

I really hope you mean 154% of the max load, and I hope that max load is engineered to be far above what should be seen in actual service. 50% over the normal service load is not what I would consider extreme, and not something I would expect to be acceptable in an aircraft.

"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."
It's literally the first sentence of the article.
I doubt Boeing were pushing the envelopes further than the FAA required. And a door fell out.
