Passenger jets get anti-missile devices
By Mimi Hall, USA TODAY
WASHINGTON — Tens of thousands of airline passengers will soon be flying on jets outfitted with anti-missile systems as part of a new government test aimed at thwarting terrorists armed with shoulder-fired projectiles.
[...] The device works with sensors, also mounted on the plane, that detect a heat-seeking missile and shoot a laser at it to send the missile veering harmlessly off course. [...] "this is the first time these systems have been tested on actual passenger airlines in commercial service," says Burt Keirstead, director of commercial aircraft protection at BAE Systems, which developed the anti-missile device.
[...] Although there has not been an attempt to take down a jet on U.S. soil with a shoulder-fired missile, Homeland Security has warned about the possibility because the portable, lightweight weapons can be bought on the black market for as little as a few hundred dollars.
[...] The Defense Department uses laser-jamming technology on its planes, but using the systems on commercial airliners is much more controversial because of concerns about cost and maintenance.
"If this is going to break down every other month vs. every fifth year, obviously that's a big, big difference," says Jim Tuttle of the Homeland Security Department's Science and Technology division.
[...] American Airlines spokesman John Hotard says company officials agreed to participate in the tests in case Congress eventually requires airlines to install the devices.
