I know the earth is Round because:
1.- I flew a Jetfighter in southamerica, near to 60.000 fts, and saw the earth curvature. (4th group-IV Brigade FACh- In Punta Arenas-Chile) this city is the more austral in the world. near to Antartica.
I too have flown in Jet Fighters. It's a good thing unsubstantiated claims on the internet don't count for much on the internet- otherwise every employee in the history of NASA would have posted here.
That doesn't mean that you were at the top fo ceiling flying on a jet fighter. I was a pilot of "CHILEAN AIR FORCE", I did things on my jet that you couldn't do as civilian. I don't care about NASA, Chile is an independent goverment that doesn't have business with NASA nor another space agency. Visit Chile and Chilean Antartic territory. Chile have Continental territory, Antartic territory and insular territory. don't believe in my word, don't care really, but answer me the things I say about the FE Map.
2.- Live in the most large country (north to south) in the world, and traveled accross in car, From Arica to Chiloe- In Plane (Comercial and Military) From Arica (north) to Antartica (South) more than 6.000 km from North to south (and I saw the time and other stuff that can be prove and demostrated by RE maps).
3.- Your map is less than accurate in show the real size of Argentina and Chile (that's is so important) Earth is not only the north hemisphere, so you are wrong there. Show an accurate FE map what can prove the real distance that I know by empiric experience of southamerica.
The current FE map is only an approximation, and many here believe some of the details on that map are fundamentally wrong. For example, a ot of us think the earth may in fact look something like this:

All of these maps are based on RET projections, so some degree of distortion is to be expected.
Once again, your map is wrong, Southamerica in this new map is much longer and so thin, Chile in this new map is longer than Africa, so was to be 8.000 km long, 4.000 km longer than continental Chile territory. And the distance between Lima and Rio de Janeiro has to be a few hundred miles, not the 3.700 km that I know.
Please stop deforming my continent and my country, my house suffers with the modifications.
...so some degree of distortion is to be expected.

?
Is so wrong and distorted.
