The Transportation Security Administration has begun a slow rollout of high-tech body scanners. The machines give screeners the ability to see beneath a passenger's clothing while they search for weapons.
At Kennedy Airport on Friday, select passengers at the American Airlines terminal were asked to step inside a big X-ray machine and raise their arms after passing through the metal detectors.
The devices use a low dose of radiation to create a computerized image of a person's body. It's seen by a worker sitting in a windowless cubicle.
