I don't know if you have ever wondered why flags like JumpjetTurnRate and JumpjetAccel seems have no effect. The fact is WestWood spelt them wrong.
I have tested the right spelt flags, and they work very nice. So it reminds me that fighters in DDay should have different TurnRate and Accel.
BTW: Besides those mentioned above, if I were in charge of DDay, I'd also give fighters Turret=yes and a limited ROT, then you have the best dogfight you can have out of jumpjets. The downside is, there may be some visal problems of open fire position. I would like to trade this for better gameplay. If you don't feel the same way, please at least fix the WestWood typo above.
