I have to agree.....and to think the A-12 was designed for the CIA 60 some odd years ago, no CAD, CAM or CATIA. Kelly Johnson and his "Skunk Works" team of engineers were nothing short of brilliant. A time when America was truly a great manufacturing powerhouse. Even though the powers that be say the SR-71's were retired in favor of spy satelite's, I can't imagine what the Blackbird was REALLY replaced by!!!!!
