Experiment: Find non-stop flights between cities in the Northern Hemisphere that go primarily West-East until you circle the entire earth.  Now do the same for non-stop flights in the Southern Hemisphere.  You will find that the flight times are basically the same.  This means that distance traveled is roughly the same since the airplanes used all have similar cruising and maximum speeds.  Please explain how the earth can be flat and yet it takes the same amount of time to travel the Northern Hemisphere as the Southern Hemisphere.

My Results:

Northern Hemisphere Route
Boston, USA to Frankfurt, Germany: 6 hours 55 minutes
Frankfurt, Germany to Beijing, China: 9 hours 10 minutes
Beijing, China to San Francisco, USA: 11 hours 35 minutes
San Francisco, USA to Boston, USA: 5 hours 25 minutes
Total Time: 33 hours 5 minutes

Southern Hemisphere Route
San Paulo, Brazil to Johannesburg, South Africa: 8 hours 25 minutes
Johannesburg, South Africa to Sydney, Australia: 11 hours 45 minutes
Sydney, Australia to Santiago, Chile: 12 hours 40 minutes
Santiago, Chile to San Paulo, Brazil: 3 hours 45 minutes
Total Time: 36 hours 35 minutes

Interesting.  Doesn't seem like you ever got a response that was able to explain it.  I'm honestly trying to keep an open mind about this stuff and listen to what these flat-earthers have to say but its really hard when they just deflect or ignore every argument or they just resort to personal attacks.

Yes, and they will sometimes engage with you up to a point as Tom Bishop did in the other thread, and then suddenly when you provide the data they have requested (or perhaps when you ask a question they really cannot answer), they stop responding to the thread altogether. I find that I can enjoy exercising my mind on here, but I do not expect to get anywhere really in terms of either understanding how the flat earth model is supposed to be possible, or in convincing anyone else to change their mind. Some of the round earth people discussing things on here are doing so because they hope to affect people who are new to the flat earth theory, when they may still be open to reason and logic.

This was the first question I had when I was looking at the flat earth map. 

I really like how on the flight path picture it shows that it would be most efficient to fly over North America to get from South America to Australia.  Brilliant!

The answer is main rounder argument: Jetstreams.

Flight time of Johannesburg to sydney is 11 hours 25 minutes. This is okey.

http://tr.flightaware.com/live/flight/QFA64/history/20170502/1710Z/FAOR/YSSY

But the opposite path:

Sydney to Johannesburg is 14 hours and 10 minutes.

http://tr.flightaware.com/live/flight/QFA63/history/20170502/0050Z/YSSY/FAOR

This is real flight time. The opposite route is manipulated by jetstreams

I'm sorry but that doesn't make sense to me.  I could run the flights going the opposite direction and the time to circumscribe the planet in the northern hemisphere would still be approximately the same as the time it takes to circumscribe the southern hemisphere (it might take a bit longer due to jet streams in one direction but the overall time would still be the same.)  If the world was flat then it would take you at least double (if not triple) the time to circle around the earth in the southern hemisphere as the northern hemisphere.

Also, did you look at the flight paths for the links you put in your post?  The flight paths don't match up for what is optimal for a flat earth.  In fact, if planes took those flight paths on a flat earth it would take even longer for them to reach their destinations.

Thank you for replying and at least giving me a possible explanation.  I think we all want to figure out the truth and the only way we can do that is straight forward discussions.

Get used to that feeling when you see Intikam posts

You're new here, you will soon see that Intikam is the wrong person to look to for straightforward discussion.  On the other forum he "proved" that the internet moves at six times the speed of light.  Nothing could convince him that it might be remotely possible his method was questionable.

Ok. You proven you are unworthy to unignored. You proven it was a bad idea to unignore you. and it was for me a disgusting experience...Now you are going to place where you deserved and accustomed.

This is to be expected.  But we are comparing North Hemisphere to South Hemisphere, not South Hemisphere to South Hemisphere while adjusting for Jet Streams.

As an example: The distance from New York City - London is ~3500 miles.  The distance from Buenos Aires - Sydney is ~ 7300 miles.  But if you look at the flat Earth Map the distance from Buenos Aires - Sydney should be 9.5x the distance, not 2x the distance as NYC - London if the map is accurate.  If you take the most "efficient" flight path on the Flat Earth, it would only be 6x the distance but then you would literally fly over North America which NEVER happens, I've flown to and from Sydney and various South America locations and we never have flown over North America.

Now on to your likely rebuttal.  The Flat Earth map is just a representation of what the flat earth society thinks it should look like.  No actual accurate flat earth map exists because....... Why?  Why has no professional geographer, cartographer or pilot produced a verifiable accurate map?  One MUST exist if flight paths, shipping paths, international borders, date lines and time zones are to be adhered to and yet all we "Round Earth Believers" can do is trust that they aren't being shown to us?  I'm not sure how you can convince anyone, even yourselves that what you are suggesting is even remotely true if you haven't seen what the Earth actually looks like.

Funny, I found this forum after calculating the same problem after a random Youtube video.   I thought Flat Earth was a joke until I googled it.   My rough calculations said a plane from Sydney to Johanasberg would have to fly around Mach 1.6 to make the trip in the time Quantas does it.  Plus flying over India and China.
