And where were you for the years prior to 9/11 when everyone else was saying that aviation security in the USA was abysmal??
Flying like you and saying cockpit security sucked, procedures sucked and checkpoints in the US were manned by a bunched of illiterate, non-english speaking idiots.
Glueball has a much more realistic approach to possible attacks in the future, especially the Stinger option
Glueball and you are right on in one scenario of the terrorists goal being that of simple destruction of an aircraft. We all know the vulnerabilities due to the different methods to achieve that goal. A gun won't do any good against a whole list of threats if the goal is just wiping an aircraft out.
The other goals of mass destruction with an aircraft are something you and many others are somewhat in pathological denial of what could happen. A gun won't help your Stinger scenarios, but it can help prevent many other scenarios that could result in an aircraft pulling a split "S" into a crowded stadium or one of our goverments.
Personally, if you don't like guns, fine.
Just don't risk the lives of thousands, nor the functioning of my goverment just to make a political point.
