Thank you for your comment but i'm a very experienced pilot. i was using this drone since 2016 (no accident) in 14 different countries , in very different scenarios (such as 25-30 knot wind speed , 2000 meters take off altitude , 90 km/s speed..etc)
flight time was right after the sunset so there were no sunlight reflection from the building (windows are dark green) , also there were enough light for the drone's obstacle avoidence system (otherwise there is a warning as you should now better)
maybe there was a obstacle avoidence system failure , i don't know , even so , as i mentioned before i searched the area 3 times.
Sir, I think one of the things you haven't come to grips with is, once you lose your telemetry signal due to it being blocked by an obstacle, there is no valid flight data on your app or in your log, even while the AC is still connected to the controller and flying happily.
Here is what happens
1) Everything is fine.
2) AC flies behind obstacle.
3) FPV/telemetery is lost. Log ends. AC is still connected via control signal and is still flying.
4) AC loses control signal.
5) RTH
If you had set your RTH height correctly, everything would be fine. But you didn't. That's an error.
You asked for help. Several people have offered their opinions.
You seem unwilling to accept the evidence. We've seen this same scenario repeated many times over the years in various forums. The conclusion is always the same - the missing or crashed aircraft is due to pilot error.
