Can you shoot a gun on a plane?
Can you shoot a gun on a plane? The cabin of the airplane is pressurized, and the hole creates a small leak, but the pressurization system will compensate for it. A single hole, or even a few holes like this, will have no effect. If the bullet blows out a window, that's a problem. A big one.
Would a bullet hole depressurize a plane?
“A bullet hole in a cabin wall would have no perceived effect on cabin pressure…. A bullet hole is far smaller than the opening of the outflow valve [through which cabin air escapes during routine depressurization].
