The higher you climb in altitude the more the earth, if a ball, would fall away from you. When you see the horizon rise up to you at high altitude that is a fact of geometry that you are looking at an extended flat plain.
This is how the earth looks at high altitude with out wide angle or fish eye lenses or photo shop.

P.S. Toward the end of the video of the Virgin Galactic flight you can see the horizon bend and see that it is a flat horizon.
Dave, once again, you've shown that you've completely ignored the evidence we gave you.
If you were to climb Mount Everest, the distance from you to the horizon would be about 230 miles, or about 370 km. On a flat earth, 29,029 ft (5.498 miles) above sea level would you well above any obstructions, and you should be able to see a lot farther than that. Not to mention that the vertical angle you would be looking would not be at 0°, it would be about -1.37°, or 1.37° below horizontal. (

So in order to look farther away, just look higher right? WRONG. 230 miles away from you on the earth is about as far as you'll ever see from Mount Everest. Because you're looking at the horizon, and because reality shows that you are indeed on a round earth, anything that you can see farther away would have it's position relative to the ground below it below the horizon.
In a moment I will edit this post to include a circle drawn on a map that shows just how much of the earth you would be able to see from the top of Mount Everest.
Here is that image:
So Dave, how do you respond to that?
