Wringing your hands like some distraught female isn't going to solve anything.. any more than watching the communist news network will lead you to the truth.

None of that is a secret, even if you did just find out about it.
Pumping a .50 cal round through the door of an airplane isn't a big deal. Besides, don't you think that with all the home grown nut jobs running loose that at least one of them has actually shot at airplanes, and have yet to hit one much less bring it down.

I've got a buddy that was a commercial airline pilot. I asked him once if anyone ever shoots at them, and he told me that every now and then they find a bullet hole in one of them. If it were flying low enough, a .308 would be pretty easy to shoot into one. Of course, you couldn't actually bring the jet down with it, unless you were "lucky" and caught the pilot in the head or something.
