Oh, makes sense.
What were they using for navigation (specifically high altitude) back in the 50s. I thought that INS was the "Nav-du-jour" back then..

This line of questioning got my fingers walkin' on Google, and found this:
http://www.sr-71.org/blackbird/manual/4/4-68.php
So, I was part correct and part wrong; the INS was one component of the attitude platform, although the primary seems to be AHRS (INS could be selected as an attitude source, in the event of an AHRS problem).
http://www.sr-71.org/blackbird/manual/4/4-3.php
INS was the primary means of navigation, and it used a star-tracker to update position and correct the drift (which I'm sure was massive with the mechanical gyros back in the day).

If that is true, I should get the thing insured. I have an autographed copy from when I was a kid and went and saw one of his presentations at the Boeing museum. My mom still remembers the ridiculous technical questions that I got up in front of a packed room as like an 8 year old and asked. I was/am a huge airplane dork though

Time to return to the saddle..
Is this where I admit that I actually have a hard book copy of Sled Driver. For real. 3 grand?

The Museum of Flight is not "the Boeing museum", sadly.

Another good read... Not too much piloting stuff but the behind the scenes stuff is very interesting. Couldn't put it down.

Colonel Rich Graham, from the BBC article at the first of the thread, has some books for less than 3K http://www.habu.org/graham/sr71flying.html. I have been to two of his speeches about the SR-71 and found them very interesting.

LORAN was land based. We didn't have many of these locations throughout the Soviet Union, China, MidEast, or South Pacific in those days.Probably LORAN..............

Oh slightly on topic, but I remember as a newly minted PPL going through the CSEL portion of my old 141 school, I did some solo out and in to BFI. Parked at the FBO, caught a ride to the museum, used the free pass, then caught a ride back to my plane. Driving the FBO ferry car was possibly the hottest girl in aviation I have ever met. We started talking about flying, as she was working on her PPL, of course with me offering the sage advice of a 1XX hour PPL. I strolled out to my plane like a boss, basically kicking the tires and trying to look cool, hopped in, started up (probably didn't even reference a checklist), and then promptly taxiied right over the wheel chocks that I had forgotten to remove. I'm pretty sure she was impressed, to say the least

When I first started trying to find a copy of the book around 5 years ago, they were priced on Amazon for between 1.5 to 3K, may be cheaper now.
I just finished up reading the book this week, and while it was awesome, I couldn't imagine it costing me $2 per page!

I recommend Paul Crickmore's Lockheed Blackbird: Behind The Secret Missions as an amazingly thorough beginning-to-end anthology and chronology of the entire Blackbird program.
I have met Crickmore a number of times when I lived in the UK and still talk to him occasionally, and he probably knows more than any other civilian on the planet about the Blackbird program (and as a British citizen, to boot!) -- he is a phenomenal individual to have pub lunch with and listen to his observations.

Yep. I have that book and the one he did on the F-117. He's thorough and technical without being the slightest bit boring.
