When a knight at a Renaissance fair in Russia noticed the drone hovering above a sword fight, he stayed in character and hurled a spear at it, nailing it out of the sky and saving the peasants from a historical anachronism. This "clash of epochs" likely won the brave warrior six hens and the hearts of grateful castle wenches, but cost the drone owner several hundred dollars.
This guy clearly doesn't mess around when it comes to immersing himself in the Medieval Era. The accuracy of that hit reveals how much practice he's put into the spear-tossing game.
Suffice to say, one does not achieve historical accuracy without the will to destroy someone else's expensive equipment.
