As I recall the sad tale of the Meteor crashes, eventually one of the investigators noticed that the wing upper surface roundels were blurred as though double printed. It turned out that the double image was caused by the wings clapping together. Apparently there was a weakness in the rear fuselage which let it hinge upward, putting the fuselage nose-up and causing the wing spar to give way and the wings to fold. Lot of aircraft and pilots lost before this was diagnosed and remedied.
PS - The other henry crun (alas no longer with us) mentions "double mainplane failure" but the cause was then unknown.
