This is how I do it.
1. Take out the Red Baron plane. Kill him head on other wise its really hard to get him.
2. Take out tanks. Be careful they can shoot you down.
3. Bomb. Be careful not to be too low, otherwise you start over..hope this helps..
Im a practice mission dropout. I never finished the first practice mission so im flying with about 1st grade education not even that.. shucks kinda like Donald. Im lvl 24 and my stats are decent
Same here with problems on this level tutorial. I have managed to take out the Red Baron and shortly after get a failed or some message of the sort. There obviously is a problem/glitch/bug on this part of the tutorial that needs serious looking into.
