Large, Non-Government Drones Flying In Mysterious Grid Pattern Over Colorado
Several of large, non-government drones have been flying in what the Denver Post describes as a 'nighttime search pattern' over northeast Colorado.
With estimated wingspans of six-feet, the aircraft have been covering 25-square-mile plots of Phillips and Yuma counties every night between 7 - 10 p.m. for around a week, Phillips County Sheriff Thomas Elliott said Monday, adding that they have received nine calls about the drones since last week.
"They’ve been doing a grid search, a grid pattern," he said "They fly one square and then they fly another square.
Nobody knows who's flying them
Several agencies, including the sheriff's office, the Army, the Air Force, the Federal Aviation Administration (FAA) and the Drug Enforcement Agency (DEA), say they have no knowledge of the mysterious aircraft or who is operating them, however Undersheriff William Meyers suggested that "The estimated size and number of drones makes it unlikely that they’re being flown by hobbyists."
Drone pilots aren't required to submit flight plans unless planning to operate in controlled airspace, such as an airport.
