Realistic crashes!
The planes crashing in IL-2 or FB, are simply a beauty to see! Turn too hard down low, a wing tip scrapes the ground, the plane pivots and fumbles over - too fast, and it blows up like AH, but when the air speed is really really low, the tumbling sequence, and the pilot climbing out of that plane to escape, is simply cool.
I've tumbled quite a few M-16s and M-3s over hills in AH, andI think the physical model is very good. Tumble, turn, and bounce on hard impact. But unfortunately, then, it just blows up!
It'd be really nice to see that sometimes your plane/GV doesn't just blow up.. seeing aircraft that go into a tumbling crash would rock!
