Here's a similar story, but about "What was the slowest you ever flew in the Blackbird?"

#12I own a print copy of this book, it's good stuff. I picked it up soon after reading Skunk Works: A Personal Memoir of My Years of Lockheed [1], an incredible book which recounts development of the U2, SR-71 and F-117A. 1: http://amzn.com/0316743003
Skunk Works is a great read. It's enlightening how advanced these guys were in the 60's, I tend to think of the 80s and 90s as being the time when we raced forward technically but it was probably the 60s and 70s were the fastest pace.
Absolutely, I found it incredibly inspirational to read about those guys riding the bleeding edge of technology - inventing and adapting as they went along.
They basically built something from the future.

I think I've read that excerpt about 5 times and I always love it!
Thanks for sharing

With a native grasp of aero / astro, can't imagine they had a lot of CAD or simulation horsepower. I have to think its a great story of fundament mastery.

As Ben Rich describes in Skunk Works, the SR-71 was designed using slide rules and drafting instruments and tested in a wind tunnel that could only run at night because of how much energy it used. IIRC it was the early stealth stuff (an SR-71 launched drone and then the F-117) that ushered in the use of computers.

#17An amazing story.

#18This is interesting for so many reasons, very good book (both in stories and writing). The most useful bit probably when he explained why the suit inflated, exactly like the way Baumgartner's balloon inflated earlier today when it reached the upper atmosphere.

You gotta love SR-71 stories.

Also amazing, was the materials engineering. SR71 ushered in the use of widespread Titanium in the airframe, which was needed to stand up to the heat (friction) at Mach 3+. Because of the severe heat-cycling, the engineers ultimately figured out an unorthodox solution to manage thermal expansion:
The fuselage panels were manufactured to fit only loosely on the ground. Proper alignment was only achieved when the airframe heated up and expanded several inches. Because of this, and the lack of a fuel sealing system that could handle the thermal expansion of the airframe at extreme temperatures, the aircraft would leak JP-7 jet fuel on the runway. At the beginning of each mission, the aircraft would make a short sprint after takeoff to warm up the airframe, then refuel before heading off to its destination.
