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.
Do both of the access doors function as blowout panels, or just the one that we know didn't open?
