The earth is round

[TheJackal]

Most flights don't guarantee the shortest distance as they are required to take a flight path that takes them nearest to other airports in case there is an emergency, this in the event that they have to make an emergency landing.. But in regards to trans Pacific and Atlantic flights, they take the shortest route, and that is usually the northern route as is notable in your link to which demonstrates that fact.. Worse still, if they took that same route on Flat Earth, it would take them longer to reach their destination, and if they took the direct straight line route, it would have taken much less time... They would never win a time distance calculation on any trans Atlantic or Pacific flights..., hence why most of their arguments involve short distance flights where time variance becomes less of a factor due to the speed in which aircraft fly, and this is because a few hundred miles in variance in their cherry picked examples won't differ much when considering short distance flights.. But ask them to do the same calculations at the average walking speed, you can then see how erroneous most of the crap they spew is.. It gets even worse if you ask them to calculate along the same parallels , that Flat Earth flight from Tiawan to LA would be hilariously long, if not beyond the fuel capacity of most airliners.
