Two days ago we lost two drones (DJI Phantom 4) in a line. The first was forced down probably by a CH-47 military helicopter that came out of the blue (no military airport in the area) and flying low over the project area (national park). That drone was found a day later.
However, on the day we lost it, we sent up a second drone to look for the first one. First, the polygon we set in DD was saved, because when we started the flight, the initial square fro flight planning came back on the iPad screen. We called the drone back, re-set the polygon and sent the drone in the air again. It worked ok in the first few seconds, then the connection was lost and it never returned. The battery was on 58% according to the control panel. We have been looking for it since then, but no success so far. Unfortunately, the last flight log was not helpful.
Now, my question related to your experience. Once a drone is lost like that, will it stay within the polygon? Or is there a possibility that at some point it simply continued the flight along one of the lines set in the polygon, but extending it beyond the limits of the polygon? Just keep flying in one direction. In latter case, I see no chance to find it…
Could you please, advise us?
P.s.: I have already contaced DD and they are working on the case, but no answer yet on that latest question.
