Seven flat earth videos in one post, plat tera! And one being a jeranism video! Boy, you've really brought out the heavy artillery!
1st vid - aside from high refractive index that day, the close photo at end of video shows how much of the bottom of the city is hidden from the greater distance view due to earth curvature. Thanks!
2nd vid - those lighthouse heights and visibility distances with the earth curve calculator, and being over water where refraction is more likely, factor in the refractive index, and what happens to light as it passes through fog, as to why the light from these lighthouses can be seen from such distances on a curved earth. Do the same with the cathedrals, and remember atmospheric conditions can bend light. Thanks!
3rd vid - not enough info on distance from camera, but if the ship is not sinking, the Earths natural curvature would explain why the lower hull of the vessel is hidden behind the water line. Thanks!
4th vid - the weatherman does a great job explaining how the inversion of cold air over the lake and warmer layer of air above, bends light and the superior mirage works. I love how nobody explains why it is bullshit, and just presses a big red bullshit buzzer for no reason whatsoever! Thanks for the video!
5th vid - a "high" five video. When not trying to prove the earth is flat, these "enthusiasts" are enthusiastically smoking weed. But I digress. The fat boy slim impersonator holding the full length mirror is flashing sunlight up over the water where there is likely a high refractive index already, and the already bent light from the viewers helps us see the large mirror reflecting sunlight. Another great video about refraction from the high five team! Yay!
6th vid - is this what dementia patients do on long flights when they get bored? There is no reference of his height, longitude or lattitude, and same of the great lakes, thus the distance away of land he is recording. It's meaningless marvellings from an old guy who likes to film in infra red and jazz it up with a bit of music.
7th vid - 121 000 feet is only 36.8 kilometers. Certainly not high enough to see earth curvature, as the vid shows, but the video looks like it's taken a lot higher. Insufficient info about this vid - sorry.
Would you like to give us a hint as to why the Earth from moon photo 1966 is suspect?
