The trees look great, which leads me to wonder if we can have non-critical/fatal crashes with them in our planes. Can we skim trees and have them brush the underside of our plane and not lose a wing or explode, or is it like IL-2 where touching an object = fireball?

Also, In the third pic posted (the lone 109 flying with the gear partially up):

There is a windmill in the bottom centre of the picture. Will it's blade rotation depend on wind speed?

Still day=no rotation
Windy day=fast rotation

Even if they're static, that's ok in my book (I just want to fly), but I was interested in how much detail you are putting into it.
