Adding new planes to existing campaigns

[DanLewis]

Hmmm. When I open FMB I get:

Load Map - Loads the bare maps used in all the campaigns and missions. There's nothing on these maps other than the geography.

Load - Loads missions (*.mis) but only the single missions, static campaigns or missions already generated / played during dynamic campaigns. I can modify the planes in these but it only affects each mission individually and not the campaign.
