Airmen roll out from the hanger a Predator UAS at Creech Air Force Base in Indian Springs, Nevada. After being launched overseas, the Predators are flown by pilots and sensor operators from ground control stations at Creech and four other Air National Guard units in the US.

Police departments are increasingly interested in deploying drones, a House subcommittee is told. As drones proliferate, so too does the 'specter of routine aerial surveillance in American life.'
