little thought, I realized that the curvature of the earth had resulted in
an illusion that the tower was extremely tall when viewed from a distance,

The curvature of the planet won't do this; it makes things seem lower, not
higher, just as a tower behind a hill might not appear as tall as it does once
you reach the crest of the hill.

However, some atmospheric effects can make things seem larger or taller than
they are from a distance.

At an altitude of 3000 feet AGL over smooth terrain, you'll be able to see the
top of a 1000' tower (but not the whole thing) from up to 92 nm away.
