Airports Utilize Old and New Security Technologies
TSA’s layered security strategy uses high-tech detectors and four-footed ones, too
Airport operators and the U.S. Transportation Security Administration (TSA) are turning to new technologies and old-fashioned strategies in an effort to thwart future terrorist attacks on airliners.
One strategy, begun last December by Edmund (Kip) Hawley, assistant secretary of the TSA, seeks unpredictability to keep terrorists off-balance and uncertain about whether any given airport on any given day will require travelers to remove their coats and shoes or open their laptop computers when they pass through security checkpoints.
“We do them [terrorists] a great service if we follow the same procedures everywhere, every time,” says Hawley. “If, on the other hand, we build a measure of unpredictability into our operations, terrorists cannot use our consistency to their advantage in planning an attack.”
Supplementing that effort, the TSA is testing cutting-edge technologies from “puffer” machines that detect tiny traces of explosives on travelers and their clothing to shoe scanners that could allow passengers to pass through checkpoints without having to remove their footwear.
