My original question was born out of my ignorance, and has been fully answered now, and I thank all involved. As a second question; I plan on flying in an area 60 miles or so north of the Gulf of Mexico, in Alabama. Even though I'm quite a ways from any military base, we routinely see military coptors, jets, and cargo planes flying what we believe to be low altitude training missions; I'm talking really low! The mature pine trees are probably 100 feet tall, and it seems these military craft, especially the coptors, are only 200 feet up or so, and appear very quickly out of nowhere. How best to stay out of their way under these conditions? Is there someone I can call when I'm going to fly? I seriously doubt they're going to give me details about their training missions. Any thoughts on this?
