  1. Or when you are flying over the Arctic. Even under clear skies looking out over the ice you can clearly see the curve of the Earth. As the sun dips down below the horizon and then comes back up, that can often feel like you are actually in space. The moon position can also help to enhance this perspective effect.

  2.  @gabahungle568  You sound just like Pope Paul V who claimed he knew more than Galileo and Copernicus. Even the Egyptians knew the Earth was round. Watch a tall-masted ship sail either towards you or away from you. The bottom disappears behind the horizon with the flag on the top mast both disappearing last and appearing first. Then you have what I call the well of Alexandria proof. In 205 BC Eratosthenes used sticks in the ground during the equinox and measuring the shadows. He got a figure within 1% of the Earth's diameter.

  3. My father A SAILOR also described the same situation when he was standing on one of the wings of the bridge on the USS Elliot.
