@Ta-bd7tx Who cares about scriptures and you are using your ignorance as a valid argument. If the Sun was local you could see it even at 4 am with a telescope according to your hypothesis, why is it not possible? It would never set, it would never get below 15,4 degrees in elevation angle, that's basic geometry. All the "flaws" you pointed out are nothing but your inabilities to grasp basic science. Water finds nothing, it's not sentient and takes the shape that balances out all the forces acting upon it, gas must not be contained, it spreads out from areas of high pressure to areas of lower pressure while within the atmosphere. Helium is affected by Gravity, what you said is embarrassing. So no, your personal incredulity, scientific illiteracy and opinions are not valid arguments.

@DaI-rx3xg I felt it every time I took off, and the instruments proved to me that I flew on a Globe so, where do we go from here? Are you about to tell me that your experience is worth more than mine? At least mine can be reproduced, just go to your nearest flight school, take an introductory flight, and witness the gyrocompass drift as the Earth rotates beneath you. If you don't think that cuts it, I suggest you go and learn how gyroscopes work. No pilot, aircraft engineer or anyone that works within the aviation industry is a Flat-Earther, so what you said is wrong, or those pilots were making fun of whoever asked the question. Science is not a religion, religion is. Besides, why did you ask someone to debate Dubay? You must think he tells the truth or that he is indisputable, therefore you trust what he says, period.

@zachisthebomb I disagree. If those flights, real life flights, check out only on a globe, then the globe must be right. The point is, even other maps have distortions and this is for the same reason, they are all planar representations of a globe. Mercatore's projection, for example, only matches real proportions on the equator, and the scale gets more and more distorted the closer you get to the poles. Same thing goes with Lambert projections, they are only realistic on the parallel of origin, then you get distortion the farther away you move from it. You can get maps that are similar to the FE which are called Polar Stereographic Charts, but they are either North or South projections and never display anything further than the Equator because it's already on the other side. Those charts are the ones with the greatest distortion and are therefore only used in rare occasions such as polar navigation.
Yes, you are right, I don't know every pilot in the world but I can easily tell you there is no way a pilot can be a Flat Earther. They are either retired with dementia or they are lying, most of the times is the latter. I have seen a video that is quite popular among Flat Earthers that shows a guy walking to the pilots in the cockpit and asking questions like "It's flat, right? Like, no curvature at all, right?" to which they reply saying "oh yes, you are totally right, flat as a pancake" or something like that. I don't think there is any doubt that they were sarcastic, you can tell by the look on their faces or the tone of their voice. Besides, according to FE's they should be paid to keep silent about it, why would they say it then? They said some pilots have lost their job after coming out about it, no sign of that anywhere. Everything we learn not only by theory, but with flying too, tells us there is no way the Earth can be flat, let me briefly tell you why:
- Navigation. First thing that pops into my head is that on a flat earth, if you wanted to fly say, due West, you would keep on making adjustments to the right to maintain heading 270, because the magnetic North Pole would constantly change its relative position from you. But in reality, this only happens in the Northern hemisphere, while on the Equator no adjustment is needed and the opposite thing happens in the Southern hemisphere, you would have to change heading to the LEFT. This alone should be enough, but I could go on with more detailed and boring explanations.
- Instruments. Small prop airplanes use gyroscopic instruments to retain information about heading or pitch and roll. A gyroscope maintains its position through inertial space, that has been demonstrated, which is why we have to adjust the gyro mounted in the gyro-compass, because the Earth spins and that spin slightly changes the indications of the instrument along the flight. It's a small adjustment, but it is needed. The artificial horizon has an erection mechanism because the Earth is round and the vertical component of Gravity changes from place to place, if it was Flat that mechanism would not be needed.
There is much more if you want me to go on, even stuff not related to aviation.
