"And even had it been unpressurized, it would have been no different than hooking it up to a 5 PSI
I do not know the size of the cargo door for that aircraft, but if it was only a modest 4' by 5' that is 2,880 square inches. At 5 PSI we have a force of 14,400 pounds! Takes good latches to hold such a door!
I have been involved with chamber doors where 100 PSI sheared off 1/2 inch bolts because someone put cheap ones on during a cleaning service. Fortunately, nobody was hurt.
Because divers work with high pressures, we sometimes get to thinking that lower pressures are not a problem, but they can be. I have seen stainless steel tubing burn like a metch in high pressure oxygen, for example. It is downright scary!
