It would go into space. The rate the earth curved downward is 8” to the mile.
Wrong. The formula is 8" per mile squared.
Even Alexa knows that...What is the curvature of the earth per mile?
The Earth has a radius of approximately 3965 miles. Using the Pythagorean theorem, that calculates to an average curvature of 7.98 inches per mile or approximately 8 inches per mile (squared).
At three miles the drop is about 6 feet. You aren't going to get that with your formula.

Interesting. Age 82 I've never thought about that. I knew
it was a globe but had never about the curvature rate.
