The world's busiest international airport, London Heathrow, unveiled a new electronic "sniffer dog" Monday, becoming the first in the world to trial the new screening technology.
The "Sentinel II" portal "sniffs" passengers as they pass through a detection arch, analyzing air that is blown across their bodies for particles of explosives or other banned substances, according to airport operator BAA.
Alongside the sentinel, BAA is testing a new three dimensional X-ray machine. Using special glasses, operators gain an enhanced 3-D view of objects in hand luggage.
