I know some are crying for gun jamming, but if you are going to do that then you would have to start modelling all kinds of anomolies that were present in every ac.
Electrical problems, system malfunctions, insufficient gear support, etc. If you just do gun jamming, then ac like the P51B will have a grave disadvantage, while other planes such as the Spits and 109's would have no problems landing - they had weak gear supports, so hey, let's be fair and model that too.
