Fighter Wing 2 "Challange 4" with 190A8

I think the game's designer threw in this level to wean players off of angles and furballs. A8 with 1 engine upgrade which wasn't necessary here.

With slower planes you can outwit the AI by going to treetop level where they get confused. But this is how you're "supposed" to win the level - just have a faster, better climbing plane.
