Living along the foothills we get a lot of low-flying traffic - usually rescue helicopters. Only a few minutes ago one buzzed my backyard no more than 300ft off the ground. So if out flying and a low-flying aircraft comes through, what is the procedure? Land if possible or drop low and hover/keep still? It would be awesome to get a few hundred yards off to one side at the same height and video it, but I'm guessing that is probably frowned upon.
