OTOH, as shown in the photo in post #142, something punctured the fuselage below the wing root and, in cruise, would presumably have caused decompression.
No, the impact damage is to the wing root fairing - that is for aero purposes and is
not structural (and is technically not part of the fuselage).
Now that being said, it doesn't mean the next time it won't penetrate the fuselage and cause a decompression - but that didn't happen on this event.
