The B4UFLY apps deal only with regulations. They have nothing to do with air traffic. The "OK to fly" result would not change if there was a helicopter hovering 10 feet overhead.
I wish I had a few more days to get more shots and angles. I really only flew for a total of about 25 minutes on this trip. I flew from 3 separate spots and managed to squeeze this tiny video out of about 8 minutes of mostly not so great footage.
