Re: How many kilometers would be possible to view in land...
That would depend on the terrain (and weather). If you're deep in a valley, you won't be able to see very far, no matter how clear the sky is. If you're on an isolated mountaintop, you could see for hundreds of kilometers if the sky is clear.
