My favorite fact about the SR is that it has to be refueled immediately after take-off since the seals leak gas like a sieve when it’s on the ground and the seals don’t close until they get heated up at altitude. At least that’s what I heard.
I don't know about the need to refuel after take off, but one of those pilots talking about flying the A 12 over Korea and Viet Nam in 67-68 mention the need to refuel both before and after their over flight.
All that info about the U2 in the 50s and the A11/A12 in the 60s at Area 51 plus the CIA flights in 67-68 were declassified in 2011. There was much published at that time including the National Geographic's show on that.

I’ve been around one the flightline back in the early 70’s, and the JP-7 just drips off the fuselage.
