NASA is less than forthcoming about a great many things, but flat Earth is not one of them. If you want to play on the fringe, then go somewhere that has a better future than yesterday's, or even today's, cosmology: thunderbolts.info. Let your future be electric, not eclectic.
What's the exact altitude one has to be to observe the curvature of a globe that's 25,000 miles in circumference? What is the exact distance something has to be for it to disappear beneath the curvature on a globe of the same size?

NASA does get distances wrong. Halton Arp discovered that the red-shift method of distance measurement had some 'shocking' problems.
