I am a pilot with an international company which sometimes flies into Olando (mco). On the way out through security I was stopped because I bleeped. I had taken my watch and all metal objects out of my pockets, so was told to take my shoe's off, frisked with the wand, belt off etc. Nothing found. as I was walking to the monorail I realised I had my phone in my shirt pocket. All that searching and they missed the thing that made it bleep. Got onto the a/c and an engineer was scrapping gum off a seat with a knife.
