Was at a construction site for work today. There were powerlines going over the site. Large high tension wires. I took off with my Mavic while waiting for my turn to get my truck unloaded and all of a sudden my camper to you bu there were power lines going over the site. Large high tension wires. I took off with my Mavic while waiting for my turn to get my truck unloaded and all of a sudden my camera view Was Upside down. So I lifted it right away. Shut it off turned it back on. Tried restarting the app a few times. Still camera view was upside down. So I left and drove down the street away from the Power lines. Camera was back to normal. I never got near the lines but I was below them. That was my only explanation to what could have happened.
