OK Folks. Here is the heavy reading. If you ever wanted to learn about the U-2 and A-12 / SR-71 programs and Area 51, this recently declassified document has it all.
1. How the only military pilots to fly over the USSR were British Pilots.
2. How Pres. Johnson misnamed the SR-71. (Should have been RS-71.)
3. How Powers was shot down. (3 SAMS one of which killed a MIG Pilot)
Enjoy
