When I was stationed at Naha Okinawa (67-69) on C-130's we had planes out looking for a SR-71 that had crashed nearby. I am not sure of the details, but the guys on the C-130's were told to look for survivors in blue flight suits that looked like space suits! I may have some of it wrong due to CRS and possibly heresay!
When I was stationed at CCK Taiwan (69-70) I went out to my airplane in the fog and when the fog lifted, there was a tow crew moving a SR-71 out of a hanger where it had spent the night. I have pictures of it taxiing by the flightline . I can't find them right now.
Also, on the subject of Blackbirds, I watched a U2 take off from a base in Viet Nam. Very impressive and I didn't have my camera with me.
I found one of my pictures of the SR71
