Several self proclaimed freedom fighters have stolen important documents with important data like the governments misconducts (corruption, drug trafficking, human trafficking, slavery, etc.). This could lead to a collapse of social order and the terrorists must be stopped.

You are Ray Gunn the best gunner available and your task is to shoot down the terrorist's cloaked vessel before they can leave the orbit. The targetting computer needs an angle and a distance to fire. It can detect by how much you missed the vessel. The vessel moves counter clockwise and slowly  upwards starting at about 200 to 400 km. The angle must be given in degrees, right is zero degrees, 90° is up, 180° to the left and 270° is to the bottom of the planet. At the top you can see the escapees progress.
