One more thing, I can not create multiple missions. (ie If i create a bomber mission out of one base, then create a fighter mission out of another base. It will not let me create subsequent misisons after the fist one. All out of one field seems to be the order.
4deck, I've posted on this subject before under 'missions: hearding cats' I believe in general discussion or help and training, I don't recall...anyway some people posted some helpful tips.
First, the old mission planner is gone and the new one is what remains. Under any 'single' mission you post, all planes have to fly from the same base and launch at the same time.
You can however, set up a 'second' mission if you want to change up times and places. I did this successfuly once, where under one mission I had bombers take off, on the second mission I had fighters/jabo's take off. The bases and times were different, but all were headed to same target.
I am not sure if your question is "can a third mission be created in addition to the first two"...I've only tried doing two at a time.
The problem I have found with multiple missions is this. It is hard enough getting people to join missions. Making two missions is even harder, and if they are counting on eachother for support, it may not work (Ie. noboby joins the bombers mission, but lots join fighter....)
I also set up mission frequency, say 'mission vox is 132'. What I have found is lots of people won't change to mission vox anyway, so I generally talk on local channel to hand out assignments. If you are launching from separate bases, the problem is appearant.
