I'm a low hours private pilot - but my training and experience to date has shown there can only be a round earth. Conversely there is a highly experienced commercial pilot on this thread saying the earth is round. All the other genuine pilots that have ever posted on this forum say the earth is round. These are all individuals with 1000s of hours of training and experience based on a round earth. A bunch of poorly educated souls watch a couple of spurious YouTube videos and they begin to labour under the misapprehension they have advanced knowledge? Mental.
You can swear and rant all you want - as long as you argue the ridiculous case for a flat earth you will always come across as the loser. You've backed the wrong horse. Keep swearing - its all you've got.
Nothing in your pilot training or anything else in your life experience shows you there can only be a round earth.
Keep telling lies.
It is what liars do.
Have a nice day, liar.
So one more before I call it a night. First off, if you want a rational adult discussion, I'm happy to oblige. Please leave the immaturity out of it. If I want a childish argument I'll call my 6 year old.
You want examples of easily observable phenomenon that cannot be explained by flat earth? I'll give you three. I have personally witnessed them all.
1 - I hope you have been on a commercial airplane before, perhaps several times, so all your arguing points come from your personal experience (if not, then shut your ignorant pie hole and get out of the room). But I'll pretend you have first hand experience with flying. The one thing any flier with a window seat can clearly see is that the apparent horizon - that is, the line where the land meets the sky - drops at altitude. What does this mean? The actual horizon is perpendicular and tangential to the surface of the Earth directly below the observer. So for an ant on a perfectly smooth surface, the actual horizon and the apparent horizon are the same. But as we ascend in altitude, the apparent horizon drops because of the curve of the Earth, while the actual horizon, that line tangential to the surface, according to basic geometry would not change. Because all of your analysis comes from direct observation, here is what you do: Get yourself a $5 bubble level from the hardware store. Just before takeoff, sight right down the long axis of the level, ensuring the bubbles indicate it is indeed level. You will be looking at or very near the apparent horizon. For grins, relate it to a fixed position towards the tip of the wing. Do it again at altitude - sight down the long axis ensuring the bubbles are level. You will find, given a sharp clear apparent horizon, that the line where the land meets the sky is well below the line of sight from the bubble level. The apparent horizon is at a lower angle, while the actual horizon, that invisible line that geometry says must be at eye level because it's tangential to the surface of the Earth below you, is still pointing to the same spot on the wing.
"But this doesn't work in clouds or because of haze or you are sitting up higher in your seat or because of perspective where we arbitrarily moved a vanishing point and changed the geometric definition of one to suit our needs" I hear you cry. That is why you must do it with a clear, sharp apparent horizon. They are not hard to see. And that is why we use a bubble level, it will give the same result independent of how high or low you shift your position in your seat.
2 - Second sunrise. If you takeoff to the west minutes after sunset from an airport on the coastline (and I have, Komatsu, Japan, runway 24 in winter where the sun is to the southwest), then you will see the sun reappear as you climb. It does not magically fade out of the mist or appear due to perspective. It rises, with the top showing, then the middle, then the bottom, and then it climbs some degrees above the apparent horizon depending on our rate of climb. Once we reach cruise altitude and level off, we are no longer increasing the dip of the apparent horizon, and the sun then sinks slowly again below the apparent horizon because the speed of a jet does not match the rotation of the Earth. If you had your handy $5 bubble level, you could observe that the entire time the sun reappeared above the apparent horizon it was BELOW the actual horizon, our friend, tangential to the surface.
3 - We have an instrument on our airplane that communicates with other airplanes, relaying position and altitude information. It is very common for me to observe aircraft near us, 1,000 feet below us, that are above the apparent horizon. They are still below the actual horizon, but they are in that area of sky above the land because the apparent horizon drops as altitude increases. It looks as though they are higher until they get very close, then the relative angle between the two planes proves they are actually lower.
Your turn.
