One of three possible outcomes: a) A passing swarm met your drone in the same airspace b) In the open space you just happened to fly into a mating circle where drones (male bees) congregate from multiple hives to await virgin queens for mating c) There is a wild hive in a tree nearby and the sound of the props was enough to annoy enough of the bees to come out and start something. As best I can tell from the footage there appears to be drone bees in the frame (rounded abdomens - they don't have a stinger like females do) so possibly you got a one in a million shot and flew into a matting circle. And if it was B like I think it was don't feel bad, males die immediately on mating, their genitals explode on climax.
