Okay... the cockpit doors are impenetrable; you're not getting in. The TSA is worried about some stuff that would not bring down a jet airliner, like a knife. Granted, looking for things that can (such as explosives) is a good thing. So, let's say I'm a "body builder". Think in terms of very muscular individuals, you could snap your neck in a heart beat. Why are they not threats? Not that I would want them to be! When does this insanity end? When do we get a clue? Perhaps some of you, and likely the TSA, do not know about the story of FEDEX 105: http://en.wikipedia.org/wiki/Federal_Express_Flight_705 Yes, it was pre-9/11, and he was a pilot / employee dead-heading in the cockpit, but the crew, despite very severe injuries took him down and landed the plane. The reality is: You're not getting in the cockpit, and the worse we should fear is a bomb getting on the plane. I doubt it will be a cup cake bomb or a knife, or a some other innocuous thing!
