Yesterday afternoon, after a normal starting procedure, my Phantom 3 Professional took off for a beautiful flight above the marsh area at Woerdens Verlaat, The Netherlands. After I took two pictures and two minutes of flight at 200 meters distance, I suddenly got an error message “Aircraft disconnected”. I pushed the go-to-home button on the screen, but it was already to late. I heard my P3P crashing and saw it falling into the swamp. I was not able to repossess the P3P, because the location is an inaccessible area. There are no boats, it is a protected area for walking. The water is too muddy and cold for swimming. So I lost it forever. Has anyone also had such an experience? It is a known problem that the P3P just disconnect? Can I claim my loss to the supplier?
