I actually made it on to a flight with.......scissors! (GASP!)
I had bought a one way ticket for me and the wife. Well, we get to the security screener and they say you have a "checkerboard" on your boarding pass, which means you have to undergo additional screening. I've flown enough so I knew we were going to be picked for the additional screening because the ticket was one way, we bought it two weeks prior, and we didn't check any luggage. Let me say right now, the whole time I was showing them my military ID. I've heard the military ID gets you out of the "special" screening, but it hadn't worked that way for me EVER. I must have made a half dozen one-way trips after 9/11, I've always shown my military ID because it's the ID that is handiest in my wallet. I've even flown one way on orders and still had the special screening.
So I get to the special screening area and present my ID to the screener. He stops, says I don't have to have undergo the additional screening, but I have to be wanded because I set of the metal detector. I've got to stop wearing a belt on planes. Anyway the guy from the x-ray machine tells the screener that I have scissors in my bag. The scissors are my wife's. She was doing cross-stitch on the trip and brought her scissors, but she put the scissors in my bag. The screener seemed to ignore the information about the scissors and sent me on my way.
While being relieved that I didn't have to undergo an anal probe because my wife didn't think about the scissors and throw them away or leave them behind like we usually do when we are flying, I was disturbed that there seems to be a special class.
