The Blackbird was a Billion Dollar Plane! The F-22 Raptor's 339 million dollar price tag seems almost reasonable in comparison to the 1960's $543,968,750 cost of the Blackbird. In CPI inflation adjusted dollars the Blackbird was over ten times the price of the Raptor. The Blackbird's successor the Aurora must have had a staggering price tag as well.

I believe that the cancellation of the Project PLUTO program, on the day of Kennedy's death, had something to do with the assassination of JFK. He was set to go after the contractors that worked on the ANP. They were looking at prison time. The Blackbird, if it had been used as planned as a bomber, would have changed the game in Vietnam as well. It is unlikely there would have been a Hanoi Hilton full of American pilots, if A-12's were doing the bulk of the bombing. The price of the Blackbird program was on par with that of the Apollo program, which was also a cover for a military program. A single Blackbird cost more than the yearly defense budget for the whole of the 1960's. The Space race was in reality a race to maintain preemptive strike superiority. Throughout the 1950's the U.S. maintained a program of "overflight" of the Soviet , utilizing Canberra bombers and U-2's. Ostensibly this program was "reconnaissance" in reality it was a psychological warfare campaign to show the Soviets that America could bomb them with impunity.
