Thnx Sturgeon. I had the offset of the target calculated as you stated and like (LOL) you I called the "fire angle" theta. Already noticed that Range dropped from the equation but was unable to solve the remaining one. To be honest, forgot all about the law of sines! Thnx a million for your help. I drew up a spreadsheet on my PDA to manage the whole thing manually. Actually more fun then lock and fire.
