(Fort Worth Star-Telegram) With a short whine and then a steady low buzz, one of the Arlington Police Department’s two remote-controlled helicopters took off for a short demonstration flight Thursday afternoon, perhaps opening a new chapter in urban law enforcement practices.

The 58-inch-long, 11-pound, battery-powered helicopters can fly at 40 mph and will be equipped with cameras. Police say they will be used for operations ranging from investigating fatal crashes on the two interstate highways that traverse the city to assessing damage from tornadoes and floods to helping search for missing people.
