Strange,
P38 is about same speed as D30 except they keep their E longer thus decelerate less. More or less depends on how much fuel you have.
And if the P38 pilot is not half of a stick, you are dead Strange.
Spiegel, as far as runing, he guy does what he has to do to survive. Maybe he was short on fuel. Maybe he knew it was you and thought he would loose. Maybe you were too warpy.
No one owns you a fight, it's raging sometimes, but you have a plane with capabilities, what u do with it to land is up to his pilot.
