The interesting thing is that its designed to be a blowout panel in the event of Rear Pressure Bulkhead blowout. This door is still firmly in the closed position. This indicates that there has not been a significant dump of cabin pressure into the H/S Bay.
There's a problem with this line of reasoning. If it's a blowout panel and it's working correctly, what, if anything (short of collision with another aircraft), could cause the tail cone to be detached from the rest of the tail in midair?
