So i was playing around with the drone on the lake… When i get a high wind warning, at that time i decided to bring the drone back to me and when i put it in reverse to bring it back it decided to fly back much faster than i expected. By the time i realized how fast it was moving… it was already too late. Crashed my baby into the lake and walked into that ice cold mess like i was Jason Vorhees to retrieve it!!!

Sorry to hear of your mishap. Check your flight log. If last entries for flight mode are autolanding is possible that you triggered autolanding. If you will get this drone again in the air or buy another one I suggest to disable landing protection.
