OSU.....Thanks for the clarification on horizon distance versus elevation. Only time I can see 2.9 mi. is on Lake Ontario, from shore or small boats,not up high (it's almost 60 miles across to Canada from my location and close to 200 miles long so there's lots of open space). Used to work with some ex-navy guys who knew the horizon distance based on the elevation of the bridge of their ship. Can't recall how far they could see but I remembered that getting a bit elevated sure puts the horizon further out there. Still can't imagine shooting 2.14 mi. even with that TAC 50 .. That had to look damn near like shooting at the horizon, or close to it...... God bless those guys and I hope they can pull off some more shots like that.
There is a rough formula I heard on the radio. You multiply the hight where you are in
feet by 1.5. The square root of that gives you
miles to the horizon.
