Files: Wings of war Collision Card System v1.02 (IT).pdf

I put my house-rule file regarding collision between two or more airplanes of WWI.
The collision management is based on maneuvers's card system.
At this time the only language avalable is italian, but I hope as soon as possible to translate it in my bad english.
Obviously I'm happy of your feedbacks to fix end improve usability of it.
