Under Predator's Watch

CNN correspondent Brent Sadler, who is on assignment in Afghanistan, tells of a close encounter with a sensor-rich Predator UAV, "the U.S. military's most sophisticated killing machine in the war on terror." With Predator, U.S. military personnel can locate and destroy targets from the other side of the world. (www.sensorsmag.com/0706/SCpredator)
