Since just before Christmas, residents of eastern Colorado have witnessed mysterious swarms of drones — sometimes as many as thirty at a time — taking to the skies in the early evening hours. The first accounts of the drone swarms appeared in The Denver Post on December 23. Business Insider reports that
Since then, sightings have spanned six counties across Colorado and Nebraska.
Phillips County Sheriff Thomas Elliott had no answer for where the drones came from or whom they belonged to but did have a rough grasp on their flying habits. “They’ve been doing a grid search, a grid pattern,” he told The Denver Post. “They fly one square and then they fly another square.”
No one seems to know where the drones are coming from, who’s responsible for them, or what exactly they’re up to. So far, the Air Force, the DEA, the Department of Defense, the FAA, and a host of other institutions and agencies (including all private drone companies known to be operating in the area) have denied involvement. Complaints have prompted a federal investigation, but thus far no additional information has been released to the public. The altitude at which the drones appear to be flying is largely unregulated.
