Thanks - already done this and am awaiting DA response, but hoping to get feedback & advice from other pilots.

Hmm, according Airdata wind was about 15 m/s in your final height and it looks like you got blown away. You were flying away with the wind and returning against the wind. Hard to tell why the signal loss occurred, could it be a collision with a high object? You had 45m height over your home point, I don't know the terrain, but if it slightly ascends you might have been only 20-30m above ground at the last known location and could have unluckily crashed into a tree. Have you searched for the drone at the point of disappearance?

Waiting for JBB* ;-)
Log looks good, no errors. At 12:30 you cancel RTH, switch to sport mode and go full throttle. Nevertheless, the drone drifts at only 8 km/h (if the orientation is displayed correctly, then even backwards ! ) to the northeast WITH the wind (click me). Is there an elevation around the tunnel ? On 7.1. at 9 a.m. the wind at your height was, I estimate, about 26km / h. BUT over elevations, ridges, etc., the wind would be stronger again, not to mention wind gusts.

If I look at the weather reports (the underneath graph comes from windfinder.com/ farnborough airport nearby), I think your MM is blown away.

Wind direction is coming from south, so your MM had to fight against the wind. And looking at the maps, the MM was at the other side of the hill. At least trees - I cant exactly see that on the profile of thiAWLYcePXqgd+/eLTL/UhV+vx/BYNDiJMDjjz/uIfP/B/EyrxteORoPAAAAAElFTkSuQmCC[/img]

Anyway, I think most errors are caused by underestimating the wind speed and directions, near high objects (mountains, buildings etc).
I suppose it "dissapeared" simply by a downforce direction of the wind, flying the MM below the objects mountain/trees and lost connection.....

So it also would might have been fighting against a down wind (see the windprofile attachment).
