Dave,

I remember being told that
some of the larger jetliners have enough bleed air capacity to maintain
cabin pressure with an entire window blown out.


AFAIK, this is a certificatino requirement and the reason why the
Concorde's windows are so small. But I've been wrong before.

One aspect not mentioned yet: It kind of depends, too, what a bullet hits
on the way out. There are some cables and pressure lines that are better
left intact. But I agree that the depressuriation is a myth, mostly. No
fat bad guys are going to be sucked out of any window, James Bond
notwithstanding.
