Aviation safety experts agreed with that assessment and said that while it is disconcerting for passengers to see any piece of the plane break, the cabin's wall panels are not part of the plane's structure.
Quite an understatement; most passengers are intelligent enough to appreciate very quickly that while the panels are not (in one sense) part of the structure, sudden and evidently noisy separation of them at one point in the fuselage might well be an indication of some kind of deformation of the primary structure.
It's a very rational fear, isn't it, even if it turns out that the cause had nothing to do with problems with the primary structure?
I would have been writing my LW&T, waiting for the fuselage to fall apart, but then I'm a pessimist by nature.
