You need a very large hole to depressurize a cabin that size.
Pressurization in an airplane is actually negative pressure.
That is, more air is pumped in to create an equal pressure within the cabin than escapes.
An airplane isn’t leak proof before a bullet hole. It actually leaks through several areas such as seams.
Now, if you open a hole the size of a door the pressurization isn’t going to work at all.
Thanks….you have “ejumakated me” some on this issue…...
