O-1 is a master @ MB. Download one of his Missions then open it with say Notepad. Look and see the structure of the files. One thing that is a huge pain is that CFS3 always puts the altitude in for you. You must edit it to what you want, each time you fly and check the Mission.
Hint: Put your Aircraft where you think you want the Mission to be based, probably near a Frontline. If not, yo can add you own Frontline. Put in about 6 waypoints in a zigzag pattern across each side of the Front. Next, save the Mission. Go to your PC, File Explorer etc, find your mission in CFS 3 "what if" ( where you saved it), and adjust the altitude. Save, then get a pilot and test fly it. Put you Z key on to note for recording your time, ( mission starts), length, altitude, waypoints,etc. Use pause a lot to freeze it and note the Lat and Long of each place where you may put a ground unit. Aircraft can be the first, or last you add. Only Edit a formation or ground unit, if you decide it must survive or be destroyed.
I average about 25 hours to build a mission. Keep your first ones short and action should start < 7 minutes. Not too many objectives either. Fill in all the briefing stuff, date, weather ( can Dl & copy it forom your "weather" folder, and save it. Then go and edit it. IF you make a mistake editing it, you will still have a virgin copy to re edit.
Good Luck.
