Not even close for the human mind to comprehend the complete structure of the planet earth, aka it’s height width and circumference. if your body your mind can’t reach the altitude it takes for your vision to comprehend the horizon curve it will look flat to you. to many of these videos people play with other people’s minds in creating these flawed conspiracies.
80,000 feet is no where near enough height to comprehend the earths structure.
In the US, "space" begins at 80.4km (50 miles), or 264,000 feet. General international consensus sets a similar limit for the start of space as 100km (62 miles), or 380,000 feet. "Low Earth Orbit" (LEO), where many satellites live, goes from 160km (100 miles, 525,000 feet) to 2,000km (1,240 miles, 6.5 million feet).
Reach where satellites roam and you might be high enough closer to the 6.5 million feet zone will give the human mind enough information for comprehending the earths structure.
