Have a look at Manu's last post, the US Navy study defines "moderate visibility" of a plane as 10-15 miles, and "high visibility" as 30-40 miles ... Sorry m8, we are far from that in this game.

Well it seems that if US Navy says that must be true.

I cannot really believe that you think you can spot a10 meter long plane at a distance of 30-40 miles which in my own lang is 65-80 Km,

Listen, i live exactly at 25 miles of a 200 meters-high buildin,g and on the best westher conditions you can hardly spot it against the sky. Imagine trying to spot a 10 meter plane, lol
