A friend of mine recently had a small bottle of liquid (shower gel or similar) confiscated by one of these anti-aircrew agents. When he asked why he wasn't allowed t take it through he was told:
"You can't take anything through that might enable you to take over the aircraft."
His reply: "I intend to take over the aircraft, i'm the ***king Captain"
The whole thing is beyond a joke now, there seems to be no consistency in the checks i go through every day. Virtually stripping the fillings out of my teeth to ensure i have no metal on my person, doesn't set the machine off one day but does the next! Sometimes it's shoes off, sometimes it isn't. Sometimes the security guy's are overbearing, jumped up, Hitler-style muppets and ............sometimes they're worse.
