There has been a bit of a furore over here concerning the new US
requirement to airlines to supply air marshals when requested. The
concern is mainly over the possible puncture of a pressure cabin.
What do readers think is the result of decompression via a bullet hole?


There won't be decompression via a bullet-sized hole. There are already a
variety of leaks in the pressure vessel. There are simply some things which
must penetrate the vessel. They're sealed reasonably well, but there's
still some unavoidable leakage. The pressure is maintained by controlling
the outflow of pressurized air. Another small hole will simply cause the
control valve to close a bit to compensate.
