TyroPicard said What? All the airliners I have flown have multiple exits for cabin air - through the toilets, vents at floor level all the way along the cabin sides, and so on. In the event of a rapid depressurisation this avoids bending the airframe.
Yes there are vents all along the floor to prevent it collapsing in the event of an explosive decompression, however they only allow the air to flow in to the freight holds thus equalising the pressure above & below, they do NOT go overboard.
