The report, IIRC, noted that some rivets had snowman holes and possibly other defects. Failure of a single or small number of rivets caused a progressive load transfer to other rivets, which failed in shear in a chain reaction resulting in loss of the skin.
It would be very interesting to see similar tests done on a group of rivets, the bulk of which were correctly driven, with one out of spec, to see just how much that one rivet changes the joint strength.
