OK... this is making more sense. I got hung up on the FAA having any real jurisdiction indoors.The “line” is determined by lawyers and often who has the most $$. I know, however, that as a commercial 107 operator, he would be held to a much high degree of responsibility. Any time you put on the hat of “professional”, you are graded much differently by lawyers and a jury. That is why I made the “foolish” comment. So many of these threads are about VLOS and 400’ without the appearance of a direct threat to people. This was different. I didn’t mean it as a personal insult. In the context of his post I think is wiser to qualify any response about the risk in addition to the legality. Flying inside in the vacinity of people is a lot different risk than exceeding VLOS in the middle of a farm field. No offense to you personally was intended.
