The Department of Homeland Security has chosen the Seattle-Tacoma International Airport (Sea-Tac) as the next site to for its air cargo screening pilot program.

Earlier this year, the Air Cargo Explosives Detection Pilot Program began at San Francisco International Airport (SFO). The program uses the latest X-ray equipment and other technology to screen air cargo.

The Sea-Tac tests will assess different technologies, the flow of cargo, speed of screening, and the effect of screening on the commercial air cargo system.
