Out of personal experience?

I've flown from Europe to the US, either the thing is round or planes like to make a huge detour over Greenland, plus jet lag and people back home claiming it's already dark etc.
And I've worked on GPS mapping software for 15 years. It works all over the world, so I guess the round ball model is correct! (We did have a slight issue that south of the equator all distances became negative but that was easily fixed)

Actually I was brainwashed from an early age with this

from what ive heard gps does not track planes when they are over the oceans...is this true ?

and how planes fly it only makes sense if the earth was flat.. it seems that most of the time they take the longer route meaning the route is bend to account for the curvature of the earth lol

And why are yu purpouselly ignoring science and scientific proves/evidence and only answering to the "if you travel around the globe" anwers.
