A couple weeks ago I was flying a mini quad copter in front of my house. I did a routine high altitude climb. Or at least I thought it would be routine. It wasn't. I reached high altitude and started a decent. Everything was as it should be. And then, it happened. The drone started drifting away from me. I fought to pull it back but I got no response. I decided to cut power, a precautionary measure. I felt it would be better to ditch it and let it hit the ground than to let it continue to drift under power. Fortunately it responded to the cut in power but it was too late. It was too high and it was falling at an angle. It fell into a tree high up and way off into the distance. I could still see it's lights blinking. I could still establish radio contact but I couldn't get the motors to pull it out of the tree. I tried to locate the tree but it was to no avail. The closer I approached the direction of the tree the lower I went in altitude and the harder it was to see. Eventually it's lights faded as it's battery drained. It is possible I still may find it. Since it is in fluorescent color I may be able to locate it at night with an ultraviolet beam. If I find it it will be plus the damages suffered by weather and rain. In the meantime I have a replacement here today. In this business we stay aloft. Occasional losses are just a part of the game.
