Don't flame me if I'm wrong... but when a 163 zooooooms by me, I'm suprised that there is not a visable rocket exhaust. We see them from RATO packs, but not the 163.
I'm not saying that it would have to stay animated for the same length of time as the real deal... but it may help the rest of us have an idea where the heck they are in a furbal....
Just a thought.
