So, you are saying that the pony should fly at 5-10 k where its performance suck?
I don't think I ever said that.
At 5-10k it wouldn't be the plane that sucks, it would be the pilot.
Altitude doesn't matter as much as attitude.
I don't care if the plane is at 5k or 20k , the intention of the pilot would be more telling than the planes performance limits.
Some of the best fights I've ever had were against ponies(and others) about 2 ft. off the deck with my LA-7, turning like our lives depended on the outcome!! Some I've won, Some I've got my donut kicked.
Either way it didn't matter, had alot of fun.
The point is--we engaged in aerial combat in totaly different planes, each with its own disadvantages, and win or lose we both came away with a sense of satisfation you couldn't possibly get from simply running away and maybe landing an easy kill or 2.
No one could possibly tell me with a straight face that the P-51 is strictly a "gun and run" plane.
A plane with such a legendary reputation couldn't possibly be that one dimensional.
