I'd never seen this before

Gee, wrong again. I haven't run the numbers, there may be a line of
sight, but the only way a human pilot would see a tower top under
these conditions is at night if it had a bright flashing light on top
of it. Real eyeballs in the daytime would not be able to see it, even
if it was in the line of sight.

An object 1000 feet in size would be visible from about 1100 nm away, under
ideal conditions. A flashing light could be visible from any distance,
depending on its brightness. I _did_ run the numbers.
