Actually, I understand that those devices that shoot darts are called Tasers, while stun guns have two metallic probes with about 20 kV across them when the trigger is pushed. Typically they are used in direct contact with the aggressor, so there would not be any live wires or darts bouncing around inside of the aircraft.
I agree with Scott in terms of holes in the aircraft skin. There presently is a controlled leak, usually in the rear of the aircraft, which controls the pressure inside. If there were some bullet holes in the skin, the controlled leak would just adjust to leak less. However, a window would be another story, but it would not be as dramatic as shown in most movies. The windows are plastic so probably would not completely blow out, but it would make a lot of noise. John Shinn, P.E.

Gregg, I believe the type of device they are talking about is the kind that shoots a projectile with two electrodes that penetrate the skin. Thin wires remain attached to the "gun" and deliver shock pulses to the cockpit invader. I think that aircraft instrumentation has enough immunity to withstand emissions from the wires. The main trouble with this gadget (most of them are one shot deals) is if the bad guy was smart enough to bring friends. As for bullets, aircraft pressurization systems are designed with excess capacity. Even a couple of dozen bullet holes are very minor leaks for such a system. There would be a problem if a bullet damaged something but large aircraft have redundant systems for almost everything. Also, they would almost certainly only use pre- fragmented "safety rounds". These are made up of very small birdshot stuck together and are designed to disintegrate on impact. I think by now it should be obvious which one I would want the pilot to have if I were one of the passengers.
