   "The FBI’s secretive spy plane program targeted a man in Florida last
   year with nearly constant surveillance, logging more than 400 hours in
   the air with a fleet of Cessna aircraft registered to what appear to be
   front companies."

   "This aerial surveillance, described in a filing made Monday in federal
   court, reveals for the first time the FBI’s enormous capacity to target
   a single individual inside the United States for prolonged monitoring
   using aircraft. The fleet of FBI planes, often small aircraft, are
   outfitted with high-tech video cameras and tracking devices known as
   “cell-site simulators” that trick mobile phones into connecting to the
   FBI’s device rather than to a legitimate cellphone tower."
