The calculation doesn't consider earth rotation (as you allready mentioned, in later cases, you also have to consider, atmosphere – temperature and humidity of the gun powder and more). While an artillery projectile is flying, the earth is rotating further. Considering a flying time of 20-60 seconds for a granate to reach a target (let's say from a M203), the rotation becomes real important if you want to hit a bridge something from 25 miles away. A task, that is possible with modern military artillery. Oh yes, there are more things to take care of… temperatur of the gun powder, direction of the rotation of the projectily (well, in artillery this is allways the same 😉 Hmm… I forgot most of that stuff… — Wolf Faust, Am Dorfgarten 10, 60435 Frankfurt, Germany —
