We watched the SR-71 take off and then it did three tower fly-bys. It was a few hundred feet out at about 50 ft AGL. We were at about 20 ft. AGL. The three passes were at 0.70, 0.65, and 0.60 Mach, in that order. They're calibrating the air data system for calibrating the OADS (Optical Air Data System). They did three more fly-bys (same airspeeds, different cg, and hence, different angle of attack) at the end of the flight, but I hitched a ride back to Dryden (from the TPS van) and went up to the control room, where they let me put on a headset and pretend to be a member of the project team. I'm not blase, I just didn't want to spend an hour waiting for it to come back from the max accels. Plus, I wanted to watch the radar airspeed calibrations. Does anyone want my aircraft instrumentation article that explains how to calibrate air data systems? It's longish, but I'll send it if there's any demand. (That's a warning--don't be too enthusiastic or you'll find this huge thing in your mailbox!)
