Apologies, but I just don't get the argument that the A-10 should be retired because it has the highest 'blue on blue' kill rate.
Assuming this is correct (and reading around the subject I'm not sure that it is), surely the fault lies with the pilots and the procedures rather than with the airframe, no?
If you assigned an F-15C to do the A-10's role, with the same pilot training regimen and operating procedures in place then I'd imagine it would have at least a high 'blue on blue' rate, if not higher.
What am I missing?
