If the "evil do'ers" are going to nuke us (or whatever) why would they be wanting to blow up a few planes?
Their primary purpose is to cause terror, hence the name terrorists.
To instill terror with the added bonus of topping the 9-11 body count is more of a bonus, would-be-nice, option.
The next attack's primary mission will be to instill terror for the purpose of making people vote against Bush. As for this "dry run", it could be just one of the attacks planned for the pre-election islamifest.
As for me, if I see this type activity going on, I will make certain that I stand in line for the restroom immediately after I notice suspicious activity, with the hope that I can possibly thwart their plan, at the very least throw them off balance. I suggest others do the same. Sitting and watching is NOT AN OPTION!!!
When I return home from work I will send you a post that best describes our present situation. Your mindset on this issue is ignorant at best.
