More like insecurity measures if you ask me. At least in USA where we tend to way overreact to past terrorism. Terrorist have won by making us take ten times longer to board airplanes than we did prior to 9/11. Stuff will happen, and I'm betting these stupid regulations won't stop it from happening. In my opinion we should dial back the insecurity measures and rely on pissed off passengers to beat the snot out of terrorist. I've seen lots of reports where someone acts up on an airplane these days and the passengers become his worst nightmare. Fool us once, but not twice kind of thing. Even on 9/11, once the passengers caught wind of what was happening on three other airplanes they acted and put a stop to it. I think it will be very difficult for terrorists to take over an airplane now as passengers are much more vigilant and much more likely to act with their own deadly force.
