$this->bbcode_second_pass_quote('Cog', 'I') believe Dave thinks if you don't continually adjust your plane attitude downward, you will fly right off the earth and into space. That is the only inference I can get from it.

Airflow over a wing is not constant. That is because the atmosphere or wind changes speed and direction constantly. Small areas of turbulence are always present with wind over the airfoil. Which is why the pilot or autopilot has to make constant corrections, not so he doesn't fly off the planet.

OK cog, I actually do have a brain. Over a distance of 500 miles there would be 31 miles of curve!!!!, the pilot I spoke to said he does not need to adjust for curvature no matter what distance .. You know when you goddamn take off what it feels like to gain altitude???????I think the pilot would need to be a bit more aggressive than a slight adjustment for wind to account for 31 F#$king miles of cuvature. Here is where you backtrack and say gravity does the rest right?

“There is a principle which is a bar against all information, which is proof against all arguments and which cannot fail to keep a man in everlasting ignorance - that principle is contempt prior to investigation”

Gravity works on the plane the same way it does every object within the earth's gravity well. Just because the plane is in motion changes nothing. Airflow over the curved surface of the wing creates lift which permits the airplane to fly. That doesn't mean the airplane is not subject to gravity. The curvature of the earth is not part of why a plane operates the way it does. Its a useless distraction.

You have heard of escape velocity flat?

Dave,
KJ AND your pilot are correct, you just can't hear anything that disagrees with your point of view.

As to why you need to answer questions it's because you are challenging a long held and EXTREMELY well proven bit of knowledge. If you have some new nit of evidence that discounts all that has gone before you the burden of proof is on you. That's just the way it works, and it makes sense or some crack pot could come along and challange that in the base ten system 1 and 1 make 2.

So there you go, you need to put up some credible information to support your claim.

So far all you have said simply does not make sense.

There is an old saying you should consider
If someone calls you an ass, ignore them.
If two people call you an ass, look in a mirror.
If three people call you an ass, buy hay.

Now I'm not calling you an ass, but a lot of folks are telling you one thing. Listen.

A majority is sometimes wrong, but the wisdom of the crowd has much more behind it than off the wall theories.

You would need to adjust over a flat world. A truly flat world would break gravity up into a repeating pattern of centers. It would do that because gravity gets stronger the closer you get to the center of mass. You get clumps. Down wouldn't just be down. My guess is that pattern would be hexagonal, developing over tens or hundreds of miles, but it might vary depending upon mass. The centers would be away from the meeting points. Crazy things would happen near the points, where there was competition from other gravitational centers. Hexagonal is evenly spaced. Things would change on your instruments over the spaces between in predictable ways. You don't observe that in our world, not even once. You'd observe much greater differences than between differing land formations which have widely different specific masses, but may occur in close proximity to each other. Even if the magnetic field was somehow moving, and taking its orientation gradually with it, as you went along, you couldn't say the same thing about what instruments sensitive to gravity were doing. Those would change more radically, or, at least, differently. Everything on earth exists around one central understanding of which way is down. Down doesn't have competition.

Flat earthers can deny it all they want. But at high altitude flight, the curvature of the earth can be seen. It can be measured in photographs taken.

Case closed.

Without math or logic. Without relying on evidence like NASA photographs (and conspiracy claims by the flat earth folks, etc).

If it weren't for so many people around here arguing for ETP theory, I'd wonder why people even pay attention to flat earthers.
