Drone swarm, which was flying over Colorado not so long ago, was spotted in other Colorado counties and Nebraska, bewildering state agencies and residents.

Following the incident, the Federal Aviation Administration launched official investigation during which the authority was lucky enough to move forward. In fact, there are two options: drone pilots had an official permission from FAA or devices were operated illegally.

On Monday the FAA and law – enforcement agencies will have a formal meeting during which they will discuss some issues related to investigation.
