FBI behind mysterious surveillance aircraft over U.S. cities

WASHINGTON (AP) - The FBI is operating a small air force with scores of low-flying planes across the country carrying video and, at times, cellphone surveillance technology - all hidden behind fictitious companies that are fronts for the government, The Associated Press has learned.

The planes' surveillance equipment is generally used without a judge's approval, and the FBI said the flights are used for specific, ongoing investigations. The FBI said it uses front companies to protect the safety of the pilots and aircraft. It also shields the identity of the aircraft so that suspects on the ground don't know they're being watched by the FBI.

In a recent 30-day period, the agency flew above more than 30 cities in 11 states across the country, an AP review found.

Aerial surveillance represents a changing frontier for law enforcement, providing what the government maintains is an important tool in criminal, terrorism or intelligence probes. But the program raises questions about whether there should be updated policies protecting civil liberties as new technologies pose intrusive opportunities for government spying.
