- U.S. forces are using an array of sophisticated gizmos
to look for Osama bin Laden and his cronies in suspected Afghanistan
hideouts.
-
- On its combat debut, the Air Force's Global Hawk unmanned
spy drone is beaming real-time video of wide swaths of territory, while
satellites are providing images of cave and tunnel openings. U.S. commandos
on the ground also are serving as sentinels for American bombers who are
pounding the hiding places with 500-pound - and bigger - bombs.
-
- Other high-tech detection devices being used
include:
-
- - Infrared light detectors that can find heat energy
emitted from cave entrances, ventilation shafts and humans breathing. These
can spot variations in temperature over distances as great as 30 miles,
with the largest sensors on aircraft also able to make out a person
otherwise
obscured by five miles of dust.
-
- The cold of winter only enhances the accuracy of these
devices.
-
- - Battlefield computers that can analyze the chemical
composition of emissions from a distant object are so fine-tuned they can
distinguish between a soldier's breath and the exhaust from a tank.
-
- - Scanners capable of picking up weak magnetic fields
generated by metal weapons or supplies hidden as deep as 100 feet
underground.
-
- - Seismic devices that send sound waves underground and
listen for echoes from caves, along with ground-penetrating radar that
similarly analyzes returning noise.
-
- - Microgravity machines that measure minute changes in
gravity's pull over caves.
