Level bombing is now possible. ATAG_Watchman recently took up an He111(H2) to 5600m and devastated a target with perfect accuracy all within the bombsite.
Now, you may not think this is much of a feat, but think about this: Prior versions of the game, the targets would not render at that type of altitude. Now while using the bombsite A.) it doesn't CTD and B.) you can visually see and set the targets with amazing accuracy.
So to all you low altitude, tree hugging bomber guys, get up to altitude and learn that bombsight!
It's the best way to avoid the flak!
