Carriage of firearms is permitted only as checked-in luggage if: the passenger has a gun licence the airline approves carriage The firearm is not prohibited or illegal. Firearms can only go as checked in luggage. You must have a gun licence Ask your airline for approval before traveling.

As one travels further above the earth, air pressure precipitously drops. The fuselage of most passenger jets Boeing for example is lined with aircraft-grade aluminum. The pressure is kept at no more than 0. When a bullet is able to penetrate the passenger cabin and push out past the fuselage, there is now a hole of the rough dimensions of that bullet. Taking the total volume of a passenger cabin and then the pressure differential caused by the hole into consideration, the proportion of that hole to the volume is not likely great enough to cause any major disturbances immediately.

The effects will be instantly noticeable, though. Thus, if the pressure in the cabin is greater than the external pressure outside the cabin, the cabin will leak air until the air pressure inside the cabin equals the outside. Based upon the second law of thermodynamics , this means that as the cabin pressure at P — pressure, T — temperature, and V — volume decreases, the temperature inside the cabin will also decrease.

At 25, feet in altitude, the ambient temperature is approximately The air pressure is also hPa — 0. So, the outside pressure of air is roughly equivalent to almost a third of what you would normally experience on the ground.
