I’m currently flying a construction site adjacent to a local airport. When powering up I will be granted my unlock code as normal. Last week I went through the motion of starting up but rather than restricting the drone from powering on, it started up. I was a little puzzled so I hovered around 50 feet agl for about a minute. I then flew to the opposite end of the site for some shots. I never got higher than 100 ft, just above the trees. Suddenly the controller alarm sounded and I got the prompt “landing”. Drone started descending straight down. I had to fight it to come back to me and was able to get it back into the opening. I brought it back to launch point, powered off, powered on and this time had to get unlock code. Completed my mission with no further incident. I’m not sure what caused this breach on the original flight.

Did you perhaps take off before getting a full GPS lock?
