The drone was 100% the reason the cub fell. You can clearly see the mother attempting to bat at the drone (failing) and the cub seemingly startled and hit with a minor amount of Bear with me beer shirt. The drone was doing a fine job filming what was happening from afar anyone with eyes can see that. So why did the pilot seem it necessary to fly is not just close but within feet of the mother and cub?

There was nothing protecting about that swing if that was the case the mother would of down that much earlier. Yet as the drone flies closer you can clearly see her Bear with me beer shirt and attitude turn to aggression towards to drone. Also if that swing hit the cubit would of knock the cub down it was a swing, not a helping hand.
Michael Patton and just to clarify I’m not trying to bash the pilot of the Bear with me beer shirt I’m simply stating that him approaching the mother and cub was careless and dangerous both for them and the drone itself.
