Well, being an ex-beekeper, now ecologist and behaviour analyst, I've found this interesting and followed it up a bit.
Wikipedia is pretty good for bee stuff.

weather - warm, still, dry. That gets them out of the hive. Then once they are away, find a queen by pheromones & vision.
From somewhere on this thread
Why do bees attack drones? Well there's a whole bunch of signals that drones give out that tell bees that they could be a threat - here we look at them all!

The top video
the guy might be a drone expert, but he certainly isn't a bee expert.
Bees will defend their own hive against vibration, rapidly moving shapes, smelly animals, etc, and then the pheromone thing kicks in, so more bees will come to help, but bees away from a hive won't attack anything. Individuals will defend themself if you grab or accidentally crush them. But the cost/benefit of defending empty airspace is negative. And the electromagnetism etc etc - pretty speculative. The study mentioned is comparable to showing that warmth is bad for you by using an oxy-acetylene torch on your arm.
The second video
clearly shows a small swarm. At 0:15 and 0:20, the bees aren't targeting the drone, they're several metres away, and nowhere near a hive.
At 1:08 he says the bees are following it. If (a big IF) that's true, it might be because there's a splattered queen on his drone. Swarms basically stay together by smell.
At 2:50, again, you can see a few bees definitely not attacking the drone. Then, at 3:30, he flies up into the swarm again, and says "Oh, we've got bees again'. At 3:55 he shows a few bees again not attacking the drone.
And if bees were really attacking something and getting smashed up, he would have been severely stung by now.
