dcs810,
I presume you are referring to my posts. Same engine, mine was a single seat aircraft though. Although the 2 seater reputedly has a better performance than the single seaters due to area ruling. It always seemed to have an advantage in combat anyway and burn slightly less fuel.
Apples with apples here, give or take a few pounds of weight. That is what doesn't make sense as AH is no fast jet novice, and very able to fly this benign aircraft. But at the end the picture must have been very wrong.
I know others have seemingly excluded the possibility, but incapacitation of some sort is the only reason I can see.
