Two of the largest pilots' unions in the nation are urging commercial pilots to rebel against current airport screening rules. In late October, the Transport Security Administration implemented more invasive patdown rules. Travelers and pilots were faced with a new dilemma -- have a revealing, full-body scan or what some are calling an X-rated patdown. Pilots are piping mad over the options, saying the full-body scanners emit dangerous levels of radiation and that the alternative public patdown is disgraceful for a pilot in uniform. Some pilots have said they felt so violated after a patdown, they were unfit to fly. The patdowns, implemented Oct. 29, allow TSA officers to pat down passengers with the front of their hands, instead of the backs of their hands. A security expert who demonstrated the new procedure on a mannequin for ABC News explained the changes. You go down the body and up to the breast portion," said Charles Slepian of the Foreseeable Risk Analysis Center. "If it's a female passenger, you're going to see if there's anything in the bra." The new patdown protocol could be used at any of the nation's 450 airports on passengers who require additional screening. Tens of thousands of passengers are submitted to patdowns and full-body scanners every day. More than 300 full-body scanners are being used at 65 airports across the country.
