Watch that and you'll see why, any day now, we'll all be stopped from flying at all over any public spaces.... I think Meigs Field (airport) is within a mile of there. Let alone the thought of that thing falling on a person, vehicle, etc. I've flown with a friend over Philadelphia at a similar height....in a Piper Cub. Hitting a TBS would have sent us crashing. He should have kept it just to the Park and very low (IMHO).
