Great question with an interesting history. The barrier between the flight deck and the cabin of commercial aircraft is engineered to blow out in a controlled fashion upon sudden decompression like the other barriers discussed in Jan's answer. However, after 9/11, the FAA mandated reinforced doors to prevent unauthorized access. These doors are much heavier ...

The internal walls in an aircraft are not designed to withstand any significant pressure difference. Since the accidents of American Airlines flight 96 and Turkish Airlines Flight 981 where explosive decompression in the cargo hold caused the passenger cabin floor to partially collapse and damage the control cables running below it, the internal walls and ...

There are two different factors to consider: First, there is the ambient air pressure - cabin and cockpit are not really separated in regard to pressure. So both would suffer from the "leak" nearly the same. On the other hand, there are wind effects - and these are considerably stronger close to the leak, especially when in front of the airflow.

Consider a similar scenario: the crew selected 28,000 feet, cruised at 28,000 feet, but then step-climbed to 34,000 feet without selecting the higher altitude for pressurization. The crew operating manual makes no mention of either scenario, unless you read between the lines. The way I tackled those scenarios is by referring to the controller logic in the ...
