Crew an SR-71, What was that like?

SR-71 Blackbird: The Crew Behind Mach 3

The SR-71 Blackbird was built from titanium, flew above 80,000 feet, traveled at more than Mach 3, and incorporated technology decades ahead of its time. But according to the people who actually flew it, one of the Blackbird's most important systems wasn't made of titanium at all.

It was trust.

In this Old Fly Guy episode from IWM Duxford, we sit down with Maury Rosenberg and Eddie McKim to explore the remarkable relationship between an SR-71 pilot and Reconnaissance Systems Officer (RSO). Separated into two cockpits and communicating only through the interphone, these two crew members had distinctly different responsibilities—but had to operate as one team.

At roughly 32 miles per minute, there wasn't much time for unnecessary conversation. Communication had to be short, precise and understood the first time. The pilot's first responsibility was simple: fly the airplane. Behind him, the RSO managed navigation, reconnaissance systems, mission progress and checklists. When something went wrong, each had to trust that the other was doing his job.

And things could go wrong quickly.

We hear what an infamous SR-71 "unstart" was really like—a violent inlet event powerful enough to throw a pilot's head against the canopy—and why the response always came back to one basic principle: fly the airplane first.

Maury and Eddie also take us inside the challenges of SR-71 aerial refueling, something required on roughly 90% of missions shortly after takeoff. With a restrictive pressure suit, limited visibility through the Blackbird's V-shaped windscreen and a tanker just feet overhead, refueling demanded another level of precision.

The conversation explores mission planning, inertial navigation, pressure suits, 100% oxygen, extreme temperatures, engine inlet technology and the extraordinary engineering solutions developed by Kelly Johnson and the Lockheed Skunk Works team. As Kelly Johnson reportedly observed, so much of what the Blackbird required simply had to be invented.

But this episode ultimately isn't about titanium, speed or altitude.

It's about two people, two cockpits and one mission.
