You cannot show a 'horizon on eye level' on that cam because:

A) it was not measured. Do they have a theodolite app on there? I didn't see one, did you?
B) The camera is not level. You couldn't measure the horizon EVEN WITH instrumentation if the instrument is not kept level. The horizon is obviously bobbing up and down throughout the video... because it's on a balloon that is not level.

Are you honestly making a claim that the horizon DID NOT drop... when you did not and could not even measure it?

I think I shall call you doctor dishonesty rather than doctor truth. Please stop making such ridiculous and unscientific arguments. It's nauseating to anyone who can see through your nonsense.
