At 0:36 he says "I shot the shore 21 miles..." but there is a) no map for reference, b) no images of the lights on the opposite shore, c) for all you know, the lights are on a hill well above the shoreline. d) light bends due to atmospheric conditions and refraction. Try doing this on dry land in a dry desert air and you will get a much different outcome. This is not proof at all. It is missing key data points to show any evidence at all. This is the definition of shoddy experiments. Why do you trust this guy?
