Very stupidly I attempted to fly in a very strong wind. 40 mph gusting. This is the very end of the flight . As usual the Mavic makes everything look quite calm. Filming the railway line below and the Mavic is going further away (wind is roughly from behind me). I am pulling the right stick right back but Drone only slows does not come backwards. In desperation I pressed RTH, as you see Drone turns and comes back and descends. I can only assume that RTH opens up Sport mode in order to give the Mavic every last bit of power to get it to return home against the wind.
