99) Viewed from a ball-Earth, Polaris, situated directly over the North Pole, should not be visible anywhere in the Southern hemisphere. For Polaris to be seen from the Southern hemisphere of a globular Earth, the observer would have to be somehow looking “through the globe,” and miles of land and sea would have to be transparent. Polaris can be seen, however, up to over 20 degrees South latitude.
Quite simply you cannot. It is widely stated you would need to be at a height of at least 40,000 ft to get even a hint of curvature if earth were round. Commercial aircraft are not allowed to fly this high. They are only allowed to fly just under this altitude. 36,000ft might be typical. In addition, the windows on commercial aircraft are small and heavily curved. Even if they flew high enough for a person to see curvature, it would still not be visible to passengers.

So, before God created land and all living things, “darkness was on the face of the deep,” a large expansive ocean. Water does not curve. In its resting state, the surface of a body of water always remain level, hence, it describes it as the “face of the deep.” It is true that small amounts of water may “curve” because of surface tension, and larger amounts of water move and “curve” when disturbed. But, the surface of all resting water is always level, flat. It does not matter how curved or rough the land is below the water.
Richard "Rick" Davies (born 22 July 1944) is an English musician, singer and songwriter best known as the founder, vocalist and keyboardist of progressive rock band Supertramp. He is the only original member of the band who is still active with them,[2] and has, besides Roger Hodgson, also composed quite a few of their major hits, including "Rudy", "Bloody Well Right", "Ain't Nobody But Me", "Another Man's Woman", "Downstream", "From Now On", "Gone Hollywood", "Goodbye Stranger", "Just Another Nervous Wreck", "Cannonball", "Better Days", "Brother Where You Bound", and "I'm Beggin' You".

25.) The surveyor's plans in relation to the laying of the first Atlantic Telegraph cable, show that in 1665 miles – from Valentia, Ireland, to St . John's, Newfoundland – the surface of the Atlantic Ocean is a LEVEL surface – not the astronomers' "level," either! The authoritative drawings, published at the time, are a standing evidence of the fact, and form a practical proof that Earth is not a globe.
