When we say down, we are talking about towards the center of the earth, the center of gravity.
No one says, "plant your feet and lower your center of density".

Note that the given minimum of 35,000 feet (10.7 km) is a plausible cruise altitude for a commercial airliner, but you probably shouldn't expect to see the curvature on a typical commercial flight, because:
- 10.7 km is the bare minimum for seeing curvature, so the apparent curvature will be very slight at this altitude.
- 10.7 km is near the upper end of the usual range of commercial cruise altitudes. Many flights won't get this high, and very few will go significantly higher.
- A passenger window may not give the necessary 60° field of view, especially if you're over the wing.
- As the quotation states, you need a nearly cloud-free horizon to perceive the curvature.
. Visually discerning the curvature of the Earth. Applied Optics, 47(34), H39-H43 ""And you can see (under ideal meteorological conditions) to a distance of 357 km"

We need to get away from the videos and start discussing this. There are multiple ways to prove the earth isn't flat by literally just THINKING about it and using some math.
Humans have known this for a long time.

Do u think it's odd the moon is 240,000 miles away, and the sun is 39 million miles away yet eclipse perfectly?.
I obviously have a ton to learn. But it intrest the shit out of me so I love learning about it .

Are you serious? If you want to learn why it's like that just look it up. The moon was much closer millions of years ago than it is today. It is still moving away from us and eventually, millions if years from now, will be too far away from earth to maintain an orbit and just float away
Why a prefect eclipse? Timing I guess. I sure the dino's had a very different and much larger moon to deal with a few hundred million years ago.

Have you looked into how the Greek philosopher Eratosthenes was able to estimate the circumfrence of the Earth? He used the angle of the shadow on a stick during the summer solstice, a well (hole in the ground), his knowledge of triangles, and the position of two cities relative to each other. It's fascinatingly clever.
You should look that up and come back with any questions!

If you get permission from the government and have a valid reason for your expedition they will let you, but they won't just drop you off and let you go wandering because if you get in trouble they have to spend millions to come and rescue you

Of course it is, you idiot A good chunk...
Like what, math? Is that all bullshit? Face it, you’re simply an idiot like retiredGreaser

How the f do seismographs and the richter scale have anything to do with a flat plane? You're spewing total garbabe misconstrued BS...
