Airport To Test Body-Scan Machines

Passengers at the Phoenix airport will start getting searched today with the help of a technology that creates revealing images of people's bodies to find hidden weapons. Travelers at the city's Sky Harbor International Airport will receive body scans from a machine the Transportation Security Administration is testing to see if it can be used throughout the USA. The millimeter-wave machine uses similar technology to a controversial X-ray scanner, called backscatter, that the TSA delayed for several years because of privacy concerns.
