Well, my worst fear happened today. It was my seventh flight. I had small trees in front of me on the bank of the Rappahannock River with my bird out about 900 feet. My video started breaking up, so I knew it was time to head back. I turned the bird around just as the DPI Go 4 flashed that comms was down. It came back up for a few seconds, as I started to worry. Comms then went down for a second time and I panicked, looking for an opening in the trees to re-connect. I slipped on a rock with moss on it and slid down a muddy dirt hill about four feet into the water. By the time I was back on my feet (mere seconds), the screen said the bird was returning home, I started to worry thinking about where I launched it. I launched it in 20 feet of clearance between tall trees and power lines. Luckily I specifically set the home point at an altitude of 50 meters. I hurriedly went to the launch point waiting for it to return, and two minutes later, it was above me. I cancelled RTH and landed it myself. The bird was safe, but the emergency room doctor said I broke my ankle. So I guess I won't be flying for the next six weeks or so until the cast comes off. To the subject of this email - The P4P is an amazing bird. Kudos to DJI for building this fail-safe into the software. It worked flawlessly and for that, I'm truly thankful... 
, but hey, you can fly from chair in the back.
