Flat Earth Theory / Re: Using airline flight data.

Latitude and Longitude lines are vertical and horizontal circles, usually illustrated as laying upon a spherical surface. The points are equidistant, and must represent spherical geometry. Arguing that the Lat/Lon system has nothing to do with a sphere is clearly incorrect.
I don't think anyone suggested that. Who are you responding to?
Any warping of them on a surface of another shape (except maybe a concave hollow earth theory) would create distortions.
I don't think anyone suggested that either.
I think the previous poster is suggesting that if you were standing on some place on Earth, and the Earth was magically whipped away into another dimension, leaving you in place, you can still determine where you are without reference to an Earth-based co-ordinates system.
You would still be at the same point in space, regardless of whether or not you had a globe under you to apply lat/long to.
You might have to refer to your position as "3 microseconds, X metres from GPS Sat A, 5 microseconds, Y metres from Sat B, and 7 microseconds, Z metres from Sat C, though.....
