I was taking some arial photographs yesterday with my Mavic Air of a pier on a seafront. Mainly flying over the sea but not far out. Also took some shots from over a pebble beach. It was foggy and very atmospheric. Whilst over the pebbled beach not very high, the lady in the Go4 app suddenly said Landing. It started to descend and there wasnt much time. I tried to gain height but it wouldnt let me, kept coming down but it did allow me side movement. I was lucky and just in time to move it a few feet on to a slipway and it landled safely. I cant be sure if I accidently activated it or not. I was planning on landing not long after this happened as battery level was getting low. I didnt have enough time and guess I was sorta in a panic I didnt pay attention if a cancelation cross was on the screen nor did I try the pause button. So not sure if they would have fixed it. I looked up some vid on here and found out how to download a flight log, which Ive done. Not that I would understand it but what is best to use to open the log. All my computers here are unable to read it. I have attached it here in the hope that someone might be able to tell me what happened (hoping it was something I did). Thanks in anticipation.
