There are at least 63 active drone sites around the U.S, federal authorities have been forced to reveal following a landmark Freedom of Information lawsuit. The unmanned planes – some of which may have been designed to kill terror suspects – are being launched from locations in 20 states.

Most of the active drones are deployed from military installations, enforcement agencies and border patrol teams, according to the Federal Aviation Authority. But, astonishingly, 19 universities and colleges are also registered as owners of what are officially known as unmanned aerial vehicles.

It is thought that many of institutions, which include Cornell, the University of Colorado, Georgia Tech, and Eastern Gateway Community College, are developing drone technology.

The authority revealed the information after a Freedom of Information Act lawsuit by Electronic Frontier Foundation. Its website hosts an interactive map that allows the user to zoom in to the area around where they live to see if any sites are nearby.

However, the FAA is yet to reveal what kinds of drones might be based at any of these locations. The agency says it will release this data later.

Most of the drones are likely to be small craft, such as the Draganflyer X8, which can carry a payload of only 2.2lb. Police, border patrols and environmental agencies, such as the National Oceanic and Atmospheric Administration (NOAA), could use for them effectively.

While few would object to vast open areas being monitored for wildfires, there are fears of privacy violations if drones are used to spy over cities. Other drones – likely to be operated only by the armed forces – might include the MQ-9 Reaper and the MQ-1 Predator, which was used to kill American Al Qaeda boss Anwar al-Awlaki in Yemen last September. source – Daily Mail UK
