Wonderful vid, thanks again to ROSS_DiFiS!
The dogfighting looked great, even though I'll have to recommend that RD uses a bit more of a wide-angle view to improve his situational awareness...

Also that hissing sound from the engine would be a good signal to turn homewards, I should say. It seems the SPAD didn't feel like dogfighting more either. I wonder why he started flying just straight and level like that, and hope it was because of some plane damage.
I was disappointed to see that a landing amid all those craters could be pulled off so easily. That texture should go together with a sure-fire broken undercarriage for anybody trying to land on it. I realise it would be a bit much to ask for that many 3D craters, but at least the coding could connect that texture with "very rough terrain" that one couldn't land on. Would give all pilots a much better incentive to break off fights and try to get across to their own side, if necessary.
Also, in general, I feel that that texture is a bit over the top, to signify no-man's-land. Yes, in the mud at Paesschendale it did indeed look like that, but I don't think no-man's-land all along the front was so peppered with shell-holes.
Those are all details, in general it was a great movie, and the balloon blowing up looked very good.
