It’s a great video, well made and interesting. Christopher, it’s not worth endangering the lives of others that might be involved in the recovery of an injured person in a compromised position or worse still a body.
Be careful out there people, your systems are just stuff. If you look through the video comments another YouTube user had the same experience at the Grand Canyon and his Phantom was stolen before he could get it recovered by a climber. Perhaps DJI should extend their no fly zones to include national parks.
