This happened to my friends Phantom (sorry I am mavic user this is why I used this forum) he claims he lost it because of wind. Some other say it was hacked by who knows. I don’t know. What do you see from video? Just like some input. Thanks.

No logs and going off of what someone says it's about as dumb as it gets.

No video posted.

You give so little information and the video you posted is of such low quality, that we don't know what makes this a weird flight path or that it disappeared.  If it "disappeared", did you look for it where the map puts it?  What part of the flight was "weird"?

Like I said is a friend phantom and I am trying to help. He doesn’t speak English so is difficult to get information. What I understand is that he says the wind was 60/k and the drone couldn’t resist and basically was out of his control and flow away.

If it is possible to get them to upload their FlightRecord from their phone to the following site and post the URL, that would be very helpful.  I'm afraid the video is of such low quality, it is nearly impossible to see any of the telemetry data.

However, if the wind speed on the ground was 60km/h, then it would have likely been blowing significantly harder the higher up they went.

In that situation, they should have immediately tried to start losing elevation to try to get to lower wind speeds and potentially kicking it into Sports mode in an attempt to get more power to try to combat the winds.
