I was at about 5k with with about 5 planes the other day near our base. Basically we were base hugging, er ah I mean defending the base.
A high F4U came in at about 12k, though the better of it and flew off.
You should have heard the whines about him being a coward.
Imagine that, he didn't want to dive down and be gang banged.
Under the same circumstances I would have gotten out of Dodge too.

Also considered cowardice is someone with 4 bogeys on his butt chasing him towards home. How dare he not turn and get gang banged, er ah I mean fight like a man??
I get tired of pack hunters complaining when a bogey won't dive down and get ganged.
