“I think the probability is low if I stick close at the entry. The other issue with the drone is the limited space. The camera will capture very little that near to the ceiling in a pass, and if I don’t follow a strict grid path, I could easily miss something,” he answers. He might have more confidence in the signal if he had gotten a drone down this way previously. As for pathing, that will be a challenge with the curvature and spacing. He can do it, but it will take a long while.
