Is there a way to just update the airplanes in front of the hangars without the parade on the landing strip?
Yes, I have found the way, but... We should have to modify all global_layer.csv files for each period (12 files) - to manually add an individual name for each airfiled. Next, we have to compile new gsl.lib file for each period (nothig to worry about - quite easy process) and create/modify/copy for each arfield <airfiled_name>.xml and <airfiled_name>.mos files. That is all. Then it would be ready for historically correct parked plane insertions by Mission editor.
So, any volunteer willing to help me with MS Excel and Notepad editing ?
