As already noted by Whels A83 has an invisible runway/hangers/ack which makes it virtually impossible to kill/capture. Ack can be killed but you have to guess where it is.
P120 is not on flat terrain which causes wings to break as you take off, there's a fair amount of obvious water not 0 around that island too.
As these are just from the small area I was playing in this morning I assume there are more. Please review this map because as good as the design may be the bugs are outweighing the good design IMHO.
