What will (or can) happen to someone if they were stupid and used their drone for 15 min at a wedding they were hired for and did not realize he/she was 4 miles away from an airport in Class C airspace? Now, no judging. Please. It was a mistake since the client was a friend and kept asking to see the drone work. Can this person be in trouble in any way after the fact? No "near misses," but noticed the aircraft were landing in this route. 4 miles out, probably 1000-1500 ft. Drone never went above 400. Does the tower see it? Would anyone report it so far out? I am having less fun with this thing the more I worry about where I am.
