Drones face all kinds of airborne adversaries from gun-toting quadcopter hunters to hackers to other flying contraptions. And it looks like nature is contributing its own flying obstacle as well, in the form of a swarm of angry bees. So who wins in the war of propellers vs. stings? Well, duh.
Why are they attacking? Who knows. Hopefully they learn their lesson before drones start taking to the skies in droves though. Like bees weren't having enough trouble as it is. Good luck little dudes, and try not to be so hostile to the new guys. [h/t Luke Hopewell]
