I just wanted to make a list and discovered the following:
A-1H Skyraider crashes when selecting MiG-CAP as Mission Type. Works fine with the other 4 (Strike, CAS, Iron Hand, Armed Recon). For some aircraft I don't get a mission type at all: E2-C HawkEye, Bell Model 47D, KA-6D Refuel Intruder, UH-1B Huey. All of these CTD when clicking 'Accept' on the 'Create Mission' screen. In the Vietnam terrain they seem that MiG CAP will be assigned to them by default.
I just added CAS,RECON and TRANSPORT as Primary Role to the UH-1B and now it flies on the range! Guess that's one fix for it. Or is there a way to allow RECON and TRANSPORT missions on the range?
