“and the plane went on to spy for the CIA until 1974”
They were operating them through the 80s because i used to see them fairy constantly coming into Burbank right past where I kept my airplane in the middle of the night with no lights for maintance at the Skunk Works.
I think some are still flying but for NOAA or NASA doing scientific research.
Or is that for the NSA? Same difference, I guess.....
Obama is operating them now.
