I think this is just kinda fun/unique to watch. I have a DJI Spark drone (the DJI Sparks are an amazing value) and I was given permission to use it to record video at this past weekends DC Taekwondo Open & Kukkiwon Cup. We received a ton of questions from people at the tournament about the use of a drone to record tournament video -- in fact, I think this might be a trend that catches on bigly. Using a drone to record tournament video certainly provides a unique angle on the action. And the drones themselves are becoming super-easy to fly, and fairly affordable. As an example, the DJI Spark does automatic station-keeping -- when it's indoors, it uses its downward-pointing sensors to automatically maintain a stable location -- you don't have to touch the controls. (When its outdoors, it uses its GPS for station-keeping.) Now I'm wondering what'll happen in a few years when 20 people all show up at the tournament wanting to fly drones...it may become another thing that tournament organizers need to manage.
