Flight due south over south pole
« on: October 29, 2019, 09:17:53 AM »
What will it happen if a plane , let's say from South Africa, will fly due South with a heading of 180 and fly over South pole? What will it happen? Where it will end up? Will it fall of ? Go into space? What?

It will not be able to continue flying straight and will have to turn around.

Why would it "not be able to continue flying straight and . . . have to turn around"?

Why not fly straight due south over the South Pole and then continue due north?

Still , what will a pilot find when over the south pole? He is Not changing his previous 180 heading and he is not turning around.  . Hit the wall?  Fly over ? Fly into space? Fall over the earth?

Exactly. Once over the South Pole, the plane is no longer flying due south at a heading of 180 as the OP stipulates. It has previously been flying straight, but can no longer do so to maintain a due south heading and so must turn around to continue heading south.

Around the poles you use grid navigation. Because of the huge vertical force of the south and north poles , the compas is not reliable anymore. It will just point down. That s why , when you are close to south pole or north pole, you are relying on grid navigation. For that , a gyroscope is being used to cross the north and south pole. You allign it with the meridian 180 and it will keep the same alignment and dirrection( search the features of gyro's ) independent of the compass or the aircraft movement. So you will continue to fly in the same direction, not turning. Again ... i will not turn. I want to fly straight through the South pole. Straight through the end of the Earth . Where will i go?

the answer depends on whether the flat earth is finite or infinite. to me both are possible. According to finite theory, you'll hit something what you hit after you go up 50 kilometers. If it is infinite, you will continue until the aircraft's engines are frozen. but after a certain point you will not be able to progress because of the cold. the only way is not to fly, but to go by underground.

The easiest way to prove your theory will be to actually go to the south pole or go in space. Second option is not that easy. So only the fist one is doable. From 30 milion Flat earth believers, is there anyone who actually have seen and documented the south pole with actual footage ?

our friends who try it reported they face various problems related the areas being secured. a globalist sailor said he will sail from new zealand and arrive in Chile after a while. He is missing since two years.

You can reach the works of the flat earthers on this subject via internet, ie youtube, facebook and twitter.

Wrong. The answer depends on neither of those things because there is no flat earth. If the plane passes over the South pole and does not change direction, it is heading North.

No. You are wrong. This is the flat earth society and oper asks it depends on flat earth theory if he does not say anything about it. Hence, my explanation depends on flat earth theory is true, and your so called explanations are null, only valid in the globe earth society, it is not here. You are on wrong forum, or confusing where you are, miss Saddam.

Although terribly interesting, this has nothing to do with the original question. You didn't ask about magnetic navigation, you asked about what happens when you travel in a specified direction.

When you specify that you are heading south, the instant that you travel over the South Pole you are no longer traveling south. You must turn around if you want to travel south.

Circumnavigation of the South Pole has been achieved, and that is passing over the south pole continuing out the other side, you can google search and find a number of flights.

Flat Earth, is a false reality.

Alright then . All i wanted was to state  that i don't want to change the 180 heading ( south heading ) and just continue to fly over the south pole . Maintaining the same direction as the meridian i am on. Where will i go ? I don t want to turn. I just want to go straight over the ice mountains or whatever it is being thought to be there. Where will i go?

You continue to state contradictory things. You stipulate not changing the 180 heading (south heading), maintaining the same direction (180 degree heading, south), but not turning. By definition, if you want to maintain the same 180 heading, you must turn.

You do realize that the direction of something depends on where you are, right?

Those flights are conspiracy. Claiming some flights does not magically make them reality. you can't make up fake flights to deceive us about your imagined world. you can't convince us with that. you need to prove their existence, just as follows.:

If you would understand some basics about navigation you will understand how a gyro will work over the north or south pole. Anyways . Forget about heading . You just follow the meridian . You start from South Africa. And you follow the same meridian's line towards south pole. After you see South Pole at your 12 o'clock you continue straight ahead . No turning . Where will you reach? The question can't be clearer than that

On a globe earth, you reach outer space.
Really?
When flying "continuing straight ahead" would imply maintaining the same altitude would it not?

So "On a globe earth, you" do not reach outer space but having passed the South Pole fly due north.

Flying south from, say, Cape Town could be flying south along the 18.6E meridian and on passing the South would be flying north on the 161.4W meridian.

If you would understand some basics about navigation you will understand how a gyro will work over the north or south pole. Anyways . Forget about heading .You just follow the meridian. You start from South Africa. And you follow the same meridian's line towards the south pole. After you see the South Pole at your 12 o'clock you continue straight ahead. No turning. Where will you reach? The question can't be clearer than that
On a globe earth, you reach outer space.
Really?

Your have been flying the same altitude for hours, why would you change altitude?

Traveling in a straight line and maintaining altitude are for the most part mutually exclusive on a globe.

Traveling in straight line means following the great circle.
Maintaining altitude means keeping the vertical distance from the datum.

Strictly mathematical representation of straight line is something else.
I don't have to fight about anything.
These things are not about me.
When one points facts out, they speak for themselves.
The main goal in all that is simplicity.

For once, I have to agree with John Davis.

The general definition (not just mathematical) of a straight line is a line that has no curvature; the shortest distance between two points.

You (and others) may colloquially use the term to refer to arcs on a great circle, and that may be fine in context, but universally declaring that traveling in a straight line "means" that is simply wrong.
