Wow pretty impressive!!! I just shot a similar video over the frozen Schuylkill River behind the Philadelphia Art Museum. I was impressed with how you were able to fly so long in a straight line. You must have shot this video on a day the winds were really calm. Usually when I fly that low to the water, I get nervous about fish that jump up out of the water. Flying over the ice I didn’t have to worry lol.Delaware River Philadelphia today I was about 10 feet off the water. Tried lower but the speed was dipping the bird too much. I fly out here all the time usually it's just water...never issues with the bird.
