Back in 1981, one of the editors of Aviation Week magazine took a "test flight" in an SR-71. It's an interesting read and includes a lot of technical detail written from the perspective of an experienced and knowledgeable pilot.
Note: Because it's a scanned image, the PDF is a bit large, about 29 MB.
A few excerpts:
"As the aircraft rolled out, Thomas applied the brakes only to find that the pedals went to the floor..." "Until they have logged 60 hours in the aircraft, pilots are restricted to shallow bank angles." "When the inlet and exhaust systems are working properly, they produce about 90% of the SR-71's thrust at cruise speed." [meaning the turbines are only producing 10 percent!] "...it is possible to get lost quickly at Mach 3..." "If the [engine inlet] spikes are as little as one-half in. out of position for a given speed, fuel flow could increase significantly enough to necessitate aborting the mission." "At Mach 3, the SR-71 does not turn very quickly, and at a bank angle of 30 deg., our 180-deg. turn described a semicircle around Boise with a diameter of about 170 mi."

I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
