What happens when you connect a chainsaw to a drone? A stunning video posted to YouTube shows the incredible and terrifying 'Killerdrone' in full flight.

The brainchild of Finnish farmers, Killerdrone is a remote-controlled flying chainsaw. The 2 minute 53 second YouTube video shows the operators guiding the drone across a snowy landscape.

In between stunning aerial shots, the video shows Killerdrone slashing icicles from a building’s roof and cutting the tops off trees. Like something out of a sci-fi horror movie, the drone also unleashes its chainsaw on some snowmen – the results are scarily impressive.

Somewhat bizarrely, the drone appears to be taken down by a balloon in the video. After the remains of the balloon get caught in its rotors, Killerdrone comes crashing to the ground, much to the relief of snowmen everywhere.

The video nonetheless highlights the extent to which people around the world are experimenting with drones.

Earlier this year the Federal Aviation Administration said there are now more registered drone operators in the U.S. than there are registered manned aircraft. FAA Administrator Michael Huerta told a legal forum in February that the agency had passed the milestone last week when it topped 325,000 registered drone owners. There are 320,000 registered manned aircraft, he said.

Drones, thanks to their small size and ability to hover low over the ground, can pose a huge security headache, experts have warned.

Technologies touted to combat UAVs include a new breed of ‘interceptor’ drones. Michigan Tech University, for example, has developed an anti-UAV octocopter that uses a net to disable smaller drones.

The U.S. military is also ramping up its anti-drone efforts. In 2014, for example, the Office of Naval Research announced plans to build a laser weapon to shoot down drones.Last year Boeing demonstrated a laser cannon that could be used to destroy drones.

Earlier this year police in Holland touted a unique anti-drone weapon – a specially trained eagle.
