I have not tried to talk to you about flying, rather about the issues in become a combat handgunner who happens to flying a plane. But using your own words you reduce yourself to taking shots at me. I put this as simple as I could, I could tell everyone that a 230 grain .45 caliber bullet has a muzzle velocity of 835fps at the muzzle and 830fps at 50yards, but it starts to get dizzying. Needless to say you are under the impression that each armed person can keep their cool and control the weapon during an unknown stress situation involving humans not equipment, I have issue with that. You are one voice and actually the only voice I have seen debating the merit of this exercise. I have some pretty realistic life experience in CQB and know first hand the dangers of engaging in a gun fight in close quarters. Take your glock and glasers and go shoot a car door, if you think it is safe you sit on the other side and at 15yards I'll shoot it... I have seen a .45 go through a Honda Civic from the trunk exiting the front fender, at much farther. Glaser are telfon coated for a reason, to penetrate the leather jacket of a person and it expands when it hits the correct tissue density ie: the body.
The only real defense is a uncertain offense, if they don't know what to expect at any given time they cannot prepare for it. You seriously don't understand the resolve and experience of the people your fighting. I have seen written alittle too much here the worry about a missile up the tailpipe, if it gets to that point isn't it too late anyway? And if your spending money cannot these planes be equiped to be flown from the ground? (Albeit expensive, but possible?)
Defense works in perimeters, you have to have several layers, each insures the next is that much safer, the answers happen before anyone reaches the plane. That means, people who care about their job, devices in place to detect and prevent, training to identify red flags, alot more can be accomplished off the plane rather than on the plane.
Anyway, I think it is a combination more than a single sided solution. But I am just a former, and not really sure what I am saying, so what do I know... Maybe you should come over to
Sniper's Hide we only have some of the highest trained people around the world there talking about the issues of putting rounds on target.
