People tell me that they are going to fly it around at 4000 feet AGL. Not likely a BF could throw that high. On the opposite side of the coin, not likely they can image a BF well enough to learn much from that altitude either. With the current critical look at drones going on, they could very well develop it then not be able to fly it. A national news channel the other day listed all the near misses with drones around major airports. It is illegal to fly a drone above 400 feet right now but airliners are having near misses at 3000 and 4000 feet. A drone in a engine could crash an airliner. I do not know how they expect to get authorization to fly the Falcon at the altitudes they plan to fly it. They obviously do not know that it takes years to get the FAA to rule on anything. And when the FAA learns what it is supposed to be looking for, they will put the request in their never decide file.
