Someone apparently loves drones so much, they've been flying them randomly over the Great Plains — and freaking people out.

According to the New York Times, mysterious drones have been spotted flying over Colorado and Nebraska the past few weeks and authorities are trying to get to the bottom of the appearances. Ian Gregor, a spokesman for the Federal Aviation Administration, told CNN that they are investigating after multiple reports of drone sightings in December.

Though the drones are not violating any laws, they are making residents anxious. "These drones have made residents in our community very nervous and anxious," Sheriff Todd Combs of Colorado's Yuma County said in a Facebook post Tuesday. "People do not like the unknown as it upsets the balance of our lives. I will tell you right up front, I do not have a lot of answers for you at this time. I wish I did, but I do not."

The FAA is currently considering proposing a rule that would require the identification of unmanned drones that are flying in their jurisdiction. The public can offer commentary on the proposed change until March 2.

Sen. Cory Gardner of Colorado is ensuring his constituents that he's "closely monitoring the situation."

"I’ve been in contact with the FAA regarding the heavy drone activity in Eastern Colorado and I’m encouraged that they’ve opened a full investigation to learn the source and purpose of the drones," he tweeted.

I’ve been in contact with the FAA regarding the heavy drone activity in Eastern Colorado and I’m encouraged that they’ve opened a full investigation to learn the source and purpose of the drones. I will continue to closely monitor the situation.
