Airport boarding gate with built-in explosives detector unveiled

TOKYO —Japanese company said, Plane passengers could soon be scanned for bombs as they swipe their boarding pass, unveiling the world’s first explosive-detecting departure gate. Engineers from hi-tech firm Hitachi showcased a machine that blows a short puff of air at a passenger’s hand as he scans his pass.
It then sucks in that air along with all the minute particles that have been blown off the hand and instantly analyses whether there are any explosive substances present. All that takes about one to two seconds, short enough to keep people moving through the gate and onto the plane. This allows screening of all passengers and can make air travel safer. The device is intended as an extra layer of security on top of existing measures, such as metal detectors, pat-downs and x-ray scanners.

The gate is most effective in finding those who may have hidden non-metal-based bombs on their bodies, like the man who concealed plastic explosives in his underwear on a flight from Amsterdam to Detroit in 2009. Since the Detroit incident, searches on individuals have become more stringent to pick up people who may carry explosives on them.

Hitachi teamed up with the Nippon Signal Co and the University of Yamanashi to develop the prototype boarding gate with a 290 million yen grant from the government.
