As the Axis side, when I use the shift-right click to manually select air units to perform air transport, I notice that even with air doctrine set to 5%, and I choose say 1 Ju-52 and 1 fighter unit (usually 0 to 2% used, usually with 30-some planes), the fighters sometimes do not fly at all, leaving the transports to get massacred.
I've seen this happen a few times, I'm on 1.04.28... the fighters are certainly in range, has anyone else had this happen? Since I use air transport quite a bit, this is fairly important for me

Thanks!
