Thanks for the replies!
Regarding removing the campaign morale penalty for not flying the aircraft for too long, I asked a question ages ago when playing F4:AF, and was told that the way to do it was to name a file BFOPS.cfg, and include this line in it:
set g_nNoPlayerPlay 120
Does this trick work for BMS as well? And is there any way to eliminate the global morale modifier that comes as a result of my personal success or failure in my missions?
