Just because you're paranoid...
A few thoughts on reading this thread.
1. You either believe there is a threat or you don't. Exposure to currently available "news", or personal beliefs and opinions regarding the reasons and politics behind the threat from terrorist acts do not in themselves insulate one or ones country from said threat.
2. Countering this perceived threat, in effect hardening targets, and causing possible threats to act elsewhere or not at all, causes inconvenience, lost time, and a perception that this is all "pretty silly".
3. Is it wise to discuss possible countermeasures put in place, by a government agency or private company (your airline), measures that may be temporary or permanent, on a WEBSITE readily accessible WORLDWIDE?
I am not defending or denigrating any current security policies in place. I hope that most will realize that the reality is, there IS a threat out there. And they're reading this.
