After 23-year-old Nigerian terrorist Umar Farouk Abdulmutallab boarded a flight from the Netherlands to Detroit last Christmas with enough explosives to bring down the plane, officials at Amsterdam's Schiphol Airport decided to build a better mousetrap.
So they installed more than a dozen full-body scanners capable of detecting metallic and non-metallic materials, including explosives, gels, powders and liquids. In the 11 months that the devices have operated, Schiphol largely has avoided the privacy and safety uproar that surrounds passenger screening at U.S. airports on the eve of the holiday travel season.
Ironically, the Dutch can credit their relative success to good 'ole American ingenuity: the kind that the Department of Homeland Security is now considering. Unlike the backscatter imaging devices that provide revealing body images and which have stoked concerns about radiation, the system at Schiphol uses radio waves to detect contraband.
The Woburn, Mass., firm that manufacturers the system, L-3 Communications Security & Detection Systems, claims on its website that the radio waves are "10,000 times lower than other commonly-used radio frequency devices."
If the software identifies a passenger carrying explosives, an outline of the problem body area is displayed on a generic mannequin figure instead of on the actual image of the passenger's body. The mannequin image, which appears on the operator's control panel, "can then be used by security personnel to direct a focused discussion or search," the company website reads.
