Is this not easy to prove its false? Just take a flight from the southern tip of Chile to South Australia. If the earth is indeed flat, the flight would take 24+ hours. But since they would fly over Antarctica, it only takes ~10.

I suppose one explanation could be that the 747 flight they are in somehow gained the ability to go faster than a F16 at maximum thrust.

I suppose they would say something along the lines of "it does take a long time, but everyone's clocks are built by the conspiracy". As for why the amount of fuel used is the same for a similar trip around the arctic, that's a good question.

[DanBlake]

my reply has to do with the unexpected time difference, not the GPS. When a flight (according to the flat earth) should take 24 hours and only takes 12.

A circle is longer than a straight line, so it would explain the time difference too.
