I learned about the artificial pressurization not too long ago. But until I read your comment, I assumed that in a case like that, the inside and outside pressures would balance shortly and the sucking would cease. Now it occurred to me that maybe the pressurization system will continue to try to compensate pressure in a situation where pressure can´t be stabilized due to a broken window, which would cause the sucking to go on. Not sure if that would be the case. Anyone knows what happens?
