- 1) All large caliber (23mm and above) anti-aircraft shells have a fusing
- system that causes them to explode at a preset altitude. In theory, they all
- explode at or around that altitude, and all that's left to hit the ground is
- fragments, which won't penetrate anything signifigant after falling that
- distance. However, with the large number of shells going up, I cant imagine
- that all of them worked exactly as designed.
- The more modern anti-aircraft guns have proximity fusing in addition to
- their altitude fuses, which causes them to blow up when they come within a
- certain preset distance of a solid object, ie an aircraft or helicopter. This
- makes them much more effective against attacking aircraft, because they do not
- require the aircraft to fly through a specific altitude range to score a
- successful hit.
-
- 2) If I had to guess, I'd say the chances of taking down a plane with a handgun
- are pretty close to zero. The first thing to consider is that due to the short
- barrel length of a handgun, they have a very short effective range, and most
- people can't hit reliably at more than 75 yards. In addition, they have a very
- low muzzle velocity due, again, to the short barrel. This means that if the
- aircraft has any sort of armor, the bullet wont penetrate. If a plane took any
- serious damage from a handgun round, it was only through the extreme luck of
- the shooter.
