The fight was dieing around 80 kills or so, around the same time my patience was.  I was at 95 when I got oil leaked by a Hurri1 on an overaggressive spiral rope.  I killed him and decided to stick around with one engine to try to get 4 more kills.  With 99 kills and low on fuel, I dive down directly on top of a zeke who appeared not to see me.  As I draw in for the close shot, he pulls max Gs straight up at me.  I tater him, but he clips my left wing.  Now I have 1 engine and a clipped wing with very little fuel.  With the additional damage penalties to my aircraft, I am only able to make it within 8 miles of the base before I am forced to ditch.  Oh well, at least a ditch is survival.   

Btw, 4 hours and 10 minutes is how long it took.
