Well. I sat and thought about this for a long time, then I read Mad Flt Sc`s answer. Nope, cant follow that!!
And BLK 33, Ive heard differing answers on this, I think it depends on ambient temperature and light refraction etc, I heard on a clear day it was 26 or 27 miles, but again, Id love to hear something a bit more concrete.
Have a nice day all,
Speedy
