One note about realism and the Mossie. If you look at photos of pilots sitting in the Mossie and then compare our default view you can see that the view over the nose in reality was much better than the default in AH.
I have sat in a mossie, i think AH has it pretty much perfect with the head position moved forward. The canopy is right in your face IRL, the default cockpit view is necessary for the instruments i think.
You can raise the seat up in the 38 for a good view and still use the real gunsite for aiming.
