The last thing a drone sees.
Not everyone who flies a drone is an idiot. It just seems that way because most of the drone videos that go viral involve them being knocked out of the sky by something. At least the good ones. If the drone you're piloting winds up in a video titled "Drone vs. [anything] you're probably not helping the cause. Like the guy whose drone stars in this YouTube clip called Drone vs Kangaroo. No one clicking on the video wants or expects to see a kangaroo hurt by a drone. They expect to see a kangaroo kick the crap out of a drone. I'm happy to report that those people will not be disappointed.
The video is satisfying, but what I'd really like to see is a clip of the owner going to retrieve his drone and getting pummeled by a herd of kangaroos.
