Wiki is wrong, heheh..
As-modeled in game, it cannot climb above 30K (I've tried getting to 32k lancs in the MA before, just criss-crossed under them for 15 minutes before quitting), and if you get to 30K, you can't bank your wings to turn very easily without loss. On top of that, your "turn" is really something almost a sector wide. A few times in the FSO I've done 262 scouting in late war setups. It's a total pig up there, barely able to fly. 109K4 way way better.
Then again, bombers in this game fly higher and faster than they did in the real war, so it's not as much a slam against the 262, as it is that the buffs are just that much better.
