Super-Fast Airport Scanners Are Coming--Eventually

Some passengers traveling through Denver International Airport this holiday season are in for a treat--or what amounts to a treat in today's high-throughput, high-stress security environment. As they go through TSA screening, they'll be able to keep their hands at their sides because of a new type of rapid body scanner. Instead of standing sideways in a plastic tube while a scanner shwoop shwoops around them, Denver fliers will step between two white plastic walls, about 4 feet apart. There are no moving parts, and the scan takes less than a second; if all is clear, the passenger moves on. The Denver scanner is built by Rohde & Schwarz, which also has a system up and running in Cologne Bonn Airport, Germany.
