But nav lights on a Spam can? From ten miles? No way. Not with my eyes,
anyway.

I live somewhat near a VOR, and get a lot of traffic to and from it, flying
right overhead at my house.

In the summer I frequently sit outside with a cold one, and watch the planes
fly by. I can see them quite clearly at quite a distance, although I really
can't say exactly how far away they are.

I do see some airliners traveling overhead at somewhat over 15,000 feet, I
would guess, on their way to and from Charlotte.
