You must be old as fukk if this true.
With that said, even your beloved globe prophets like Neil DeGrasse Tyson say you can't see curvature unless you're 50+ miles off the ground. And most commercial planes only fly at about 7 miles off the ground. And the Concorde only got to 12 miles or so off the ground. So you were not close to being high enough to see any curvature. Anything you saw that looked like a curve was the result of the concave window you were looking out of. They create the illusion of curvature. People have send weather balloons much higher in the air than any plane with cameras that don't have fish-eye lens. And guess what, they showed no curvature.
According to our senses and every non-fish-eye lens camera by non-NASA sources shows a FLAT EARTH. Try me again bytch.
I'll be 40 this year.
And you got your facts mixed up.
They say you can see the curvature of the Earth at 50,000+ feet. (google it)
The concorde flies higher than that. (google it too)
And it's interesting that you appeal to the authority of astrophysicists when they say you can see the curvature of the Earth at a certain altitude, but not when they say the Earth is round.
You were dead serious too.
I love anti-intellectuals. Ya'll stupid ass talking points are like popcorn to the educated.
Keep the hypocrisy coming, breh.
