Stream you forgot this one:

"...........if I were in a 109 and wanted to attack an equal number of 51s, I would do one of two things. I would try to evade/avoid them or make a high speed dive at them, hope they did not see me, try to knock off one or two of them and keep going as fast as possible down and away from them. We could do everything better than they could so unless the pilot was a fantastic pilot, tangling with P-51s with at least average pilots was a lose-lose situation. So if they yo yo off us, we still are coming after them and they are in trouble. Check how the top German ace, Hartmann, did it. Normally a dive from 40K, hold fire until 100 meters away, fire and continue the dive away. Of course this required him to not be seen before the attack."
