It was fedex or dhl cargo plane crashed into Russian passenger plane full with children, crashed because of air controller mistake. Air controller's orders have the highest priority, and it should be so as he sees the full picture. Later father of one of the children died in the crash came and killed air traffic controller responsible, then got jailed, then moved to Russian jail, now than later freed.
It's not possible with J2ME (I've tried last summer with N82 and failed exactly as you've described. But Android is different story. Now I can do complex tracker-less recognition once every second while simultaneously rendering 3D scene on top of camera output and processing user input with 20FPS. All in Android Java. Should be even better with NDK. P.S. Your tower defence game is great, I have it on my cell since it was released first
