So Wizard of Auz you just let anyone that says they jokingly say they have a bomb in their bag on the aircraft do you? Maybe we should ask the other passengers if they still want to fly with this person onboard and see if the flight still leaves with them on it. As for the comment that no bombs have been found in the screening process I doubt that this information would be made public anyway and as the fact is that none have made there way on to any aircraft it must mean that the job must be getting done right by the security on the ground.
