Agree with a pressurised hull and what seamed to be a number of windows moving in the video shot.
How many of the missing rivets were caused by the skin flexing after the explosion??
Tests have been done previously with very differing results when the hull is partially pressurised.
It's all good info but I think what was seen on the video could possibly have been done in a lab to show the flexability of the duraluminium skin and frames.
