Lack of impact sounds?

[Psycho_Ch!cken]

I know a lot of posts have been made about sounds, or a lack thereof, but I noticed one glaring omission the other day and when it happened again just now, I thought I'd better ask about it.

When you crash one plane into another plane, there does not appear to be any sound to indicate it. Barely 5 minutes ago a G.50 plowed through my Hurricane while I was in a tight turn and took my entire tail section clean off. I had absolutely no idea that this had happened though. All I saw was that apparently I'd gone into a spin and spent the next 10 seconds trying to recover it. When it refused to recover, I cheated a little and took a look at the external view and got quite a shock to see that half my plane was gone.

There wasn't even a particularly noticeable shake of the cockpit when I was hit (head shake is on) - as I said, it was as if I'd simply made a mistake and put myself into a spin. Is anyone else noticing this total lack of visual/aureal feedback? Or am I going insane? :/
