Nor do I care, but I do know this, if the Marines had bought even one squadron worth of F's we'd have enough D's to train with for the foreseeable future in the C world and not degrade training because we don't have enough 2 seaters to train, instead we cut 2 seat hops out of the syllabus and call it good. And big Navy wonders why mishap rates are on the rise........less hours, replacing flight hours with sim time. I digress.
