PSD, Physiological Support Division, was my unit. Richard begins speaking of us @ 38:05. For the next 6 minutes you'll see film clip-glimpses of us at work. During my time we wore white uniforms. The most challenging connections were deep, one-handed reaches to hook up the two oxygen leads from the suit to the seatkit, each having a clip ring lock that must be secured after connecting the leads. It required dexterous fingers, and these connections were critical.
Any fan of the SR-71 will enjoy this interview. @1:06:20 I was especially amused when he described the MiGs (likely Foxbats) falling out of the sky one by one. There was one time they got lucky with a -25, choreographing their timing just right and managing to be above our Habu over or near Vietnam. They promptly sent the photo to the Pentagon. Lots of great stories like that.
