Knew a guy(my old boss) that was ground crew for the blackbird. Platinum o-rings, he confirmed that they leaked fuel real bad, take-off was always followed by in air re-fueling. Those engines got more efficient with altitude and the heat generated at mach3 would swell everything up and close the built in tolerances. One of my favorites and the German did it right. Did they ever de-clasify the performance numbers on her? Prolly one or two put away somewhere, just in case.
