The US Justice Department is using "feykovye" cell tower on airplanes to get free access to registration data from the phones of almost all the country's population. As told WSJ anonymous sources familiar with the secret program the US authorities, the technique of shadowing fully operational since 2007 and identifies the location of any phone with an error of only three meters. It is running the whole system like this: on the aircraft (the most commonly used small civilian aircraft company Cessna) installed special equipment - stuffed with electronics boxes in the shape of a cube. Square faces boxes are 0.6 meters in length, but the relatively small size does not prevent them to play the role of full-fledged cell phone towers. Aircraft with these devices is then lifted into the air. The operation uses five (at least) the major airports, and their location, coupled with a range of aircraft flight ensures contact with the phones of almost all of the US population
