These people are on a huge power trip.
For just a few hours a day, they get to become important, they get to feel like gods! They think "Oh look, here comes a pilot. Lets see how many items we can get them to remove".
When the crazy thing is, if I didn't want to go upstairs for something to eat or drink, I could walk straight pass the machine, and swipe myself through the door with my ID card to get to my aircraft.
Why do we even bother with having the security check to get them?
I case you haven't noticed I have had it up to here (I'm pointing at my head) with the people at the metal detectors. They have ZERO logic, I say to them "If I was going to take over the aircraft would I be, oh wait a minute, I all ready am in control of it?!"
