LA Times - The Federal Aviation Administration said it had issued 1,428 permits to domestic drone operators since 2007, far more than were previously known. Some 327 permits are still listed as active.
Operators include police, universities, state transportation departments and at least seven federal agencies. The remotely controlled aircraft vary widely, from devices as small as model airplanes to large unarmed Predators.
The FAA, which has a September 2015 deadline from Congress to open the nation's airspace to drone traffic, has estimated 10,000 drones could be aloft five years later. The FAA this week solicited proposals to create six sites across the country to test drones, a crucial step before widespread government and commercial use is approved.
Local and state law enforcement agencies are expected to be among the largest customers.
