Thank You. This is my take on it:

the wings were bent in an extreme manner.

so you have a cylinder to a close approximation, with a hole in the side of it. Then you have two levers [wings] affixed to said cylinder, then you apply force to the levers, and distort the cylinder thus distorting the hole in the cylinder....

at this point i would invoke a topological parlour trick of making a quarter fall through a dime sized hole as an analogy.

my hypothesis is that the entire airframe flexed causing the door frame to distort thus loosing its grip on the door panel


This is what I came to say, and finding validation in your saying of it, I can but say "I agree" -But I would love to see a more formal write-up of how the wing stressed area carred over into the doors, and how likely this risk is, and if its a peculiarity not previously seen because wide-scale use of composites in large-volume widebody jets is still somewhat new?

(new as in, comparatively few composite body jets at scale are being tested, few models have existed, compared to the numbers of more traditional material jets which have undergone this specific test)
