If 2 planes set off in completely different directions, both headed for Australia (and according to a flat earth) would only 1 plane make it there?
Also, if there is apparently a point on the Earth where there is a mammoth -276 degrees weather system, then where is the furthest you can possibly go? Surely someone has got close and taken photos?

I don't understand your question. If two people went to New Jersey, would one only make it? This is what your question sounds like.
-
I think he means there are 2 ways to travel between 2 places on earth. eg. Paris to Cape Town. 1) head southish, the shortest distance. 2) head northish over the North Pole, down and around.
Head north on the non existant FE map and you will hit the edge eventually.

Answers.:
According to FE you don't go in straight lines from one place to another. You always go in circles. So you would never get to the edge. According to FE if you went around the flat earth on the equator, you would always be turning. But aircraft are programmed to fool you into thinking you are flying straight. (Obviously a part of the Round Earth Conspiracy.)
It has been discredited by some FE's, but other FE's say you can't go to the edge of their flat earth is because the edge is guarded by armed guards from NASA who would shoot you on sight if you got close enough to see it. Also you can't get to the ice ring because it is so cold because it is so far from the sun. And those pictures of the ice ring are not really a close up of one of the ice shelfs on the continent of Antarctica. Stick around and you will get a lot of answers....sometimes.....but sometimes you won't get any answers at all from any FE's.

This is self-contradictory. If 2 planes set off in different directions they would end up in different places. The 2 planes would only reach Australia if they headed off in the same direction, ie. the direction of of Australia.

On the RE they would end up where they started.

I think a better way to rephrase the OP that will alleviate some of this confusion is this:
>>>If two planes leave Perth Australia, one headed east, the other west, would both planes be able to make it back to Perth without having to alter course?
(For the sake of simply sissy, let's not worry about avoiding weather systems, air traffic, tail winds, etc.)

Here is another example.:
Two planes are going to fly from Love Field in Dallas to Meacham Field in Fort Worth, about 30 miles due west.
One plane goes due east, the other plane goes due west.
How far would the plane going east have to go and how far west would the other plane have to go ?.
Which plane would get to Meacham Field first , considering both planes fly at the same speed ?
Would only one plane make it to Meacham Field according to the FE Map if you could just fly in a straight line on the FE map ?
And how would this work on the Round Earth if you just flew in a straight line on the Round Earth ?

As far as I've seen here, no accurate map of the flat earth exists, nor a map of any kind beyond a tentative doodle or a projection of a globe. That said, in principle I think the claim would be that the westbound plane would reach its destination the same as normal and the eastbound plane would do one of two things depending on how you interpret your question. East on the flat earth is just a big circle centred on the north pole so kept a constant easterly bearing by turning north as it flew its path would be a big circle around the earth roughly along the flat earth equivalent of the 30th parallel. However, you also specified a straight line, so if it set off eastward but carried on flying in a straight line it would head roughly toward the Atlantic somewhere, maybe cross some land but eventually hit the edge of the world and not take any pictures or come back again. ;)
Flying in a straight line of any bearing on a globe takes you in a great circle and you end up back where you started, excluding the rotation that's happened during the journey.
/edit, straight courses being great circles on a globe also answers Theo's rephrased question about leaving australia in two directions and getting back there without changing course. If you fly straight for 40,000km in any direction, you end up back where you started. So, yes if two planes left in any two directions you can name and flew straight, they'd get back home eventually without having to change course.

I just want to point out that on a RE globe, if you flew East from Dallas all the way to Forth Worth, you would also make a big circle and have to turn the entire time too.
Also, if you flew perfectly straight on a round Earth, you end up in space.

Yes you would if you wanted to fly along the 30th parallel heading east all the way, but you could fly without turning and still end up back in Texas.
Straight relative to the ground is how humans typically describe directions unless they're discussing a very specific field or being intentionally obtuse.
-
I agree that theoretically, if the Earth is round, you could leave Dallas flying east, never turn and make a big circle around the Earth and end up in Dallas again, but not in Forth Worth; and you would only start out flying east. You would have to turn at some point in order end up in Fort Worth, even if it is ever so slightly.
However, all this is just a theoretical mind exercise and proves nothing.
-
You could curve your course gently or fly at such a speed that the journey took 24 or 48 hours.
As for thought exercises proving nothing, some do, but not this one. This one is only about getting people on the same page.

But, that would cause you to not take a great circle course. You would have to take a great circle course in order not to turn. I believe you would have to start out flying ESE or something like. This would also be the longest direct route connecting the two cities.

Ok, let's eliminate one source of trouble from this question: the great circle course. When you think of a great circle course and how it looks like an arc when drawn on a map rather than a straight line connecting two points, this is because you are normally envisioning a Mercator projection map or something close - a map with parallel lines of longitude. So, to work around this misconception let's reframe the question again:
>>> If a plane left the North Pole in any direction and does not deviate from this course during flight, can the plane eventually make it back to the North Pole?
(Because the plane is traveling in north/south direction, the great circle route would look like a straight line on a Mercator projection map, it would in fact lie directly on a line of longitude).
The answer to this question should be straight forward: if the earth is spherical, the plane will leave the North Pole heading south, it will eventually reach the South Pole and continue flying in a straight path towards the North Pole, so the answer is yes. If the earth is flat and we envision it to look like the UN logo of a flattened earth, the plane will get to the South Pole but instead of continuing on a straight path it would encounter the ice wall/ force field/ edge of the earth - so the answer is no.

And it would be very difficult navigate down south as you could not rely on a magnetic compass to give you reliable information. How would you know if you are heading south, or north?

Using GPS.

BURN!
Also an accelerometer, a good one is even more precise when talking about measuring turns.
Also a gyroscope.

Again, you are making a theoretical argument. No RE'er or FE'er is going to spend this much money to test it. So, you are basically saying, "If the Earth is this, then you Should be able to do this." It is not really an argument. Yes, I agree that IF the Earth is round, then you should be able to fly past the south pole and start heading north.

There is no reason at all to doubt this. All dimensions fit in with a round earth and the shape of the south pole.

When? Can you provide some evidence for once this week?

Jroa: Yes, the question as stated is hypothetical (not theoretical), but the concept can be tested, and if we agree on the the predicted outcomes for FE and RE now, then when we do test this concept, we can be definitive about our interpretation of the results.
The concept in this question can be tested either by doing exactly the experiment as described, flying from North Pole to South Pole and back around to North Pole, but you are right, no one is going to invest the time and money to do this, there are not established flight routes like this.
So there is another way to test it: because the same physical principles apply whether you head north/south or if you head east/west by flying around the equator (where the great circle route also looks like a straight line when drawn on typical maps).
