Seriously, DUDE.Seriously dude I personally know two retired military pilots ,two or three civilian pilots .
Ah no .
To shoot artillery acurrateky and to actually launch proves NASA and the army account for how gravity pulls and the earths .
In my time In Afghanistan we used Russian made maps .they were as accurate as ours .no satellites used but aircraft to make them.
All military and civilian maps use the spheroid surveys made over a century ago and accounting made for noticeable changes to include runway desigmations.
That would make simple driving from point a to be problematic in how they know where to put roads .
That's why I posted it .videos can be faked .
My entire family's been Air Force for generations.
They all know it's Flat and I know far more than you do about all the other points you tried to make.
Answer the question.
Why is Flat Earth such an unprecedented threat to the status quo?
