Starting with the official Tower!3D Pro User Manual I've created an annotated version (attached to this post below) in which I cleared up typos, made grammar corrections, added airport diagrams, and aligned the descriptions to match the current visible behavior of the Tower!3D game (for non-voice recognition) and Tower!3D Pro game (for voice recognition). I think it adds some useful information to the manual to clear up confusion during play.

Enjoy!!
