Attached is a tool which will assist in creating and removing static units which will include aircraft but also ground units. After a template is created it will be very easy to modify each template allowing modified templates to be tweaked for virtually every mission if you wish with very little effort.
Included in the download is the generator tool, the LUA files for the demo mission and the misson file itself.The LUA files will need to be in Missions\Scripts but you can move them if you have even the most basic ME knowledge.............Follow the link for an overview
