I found the blog in a Google search yesterday and just thought I'd drop my link on it. I am not a C 133 vet, just a 58 year old guy with a strong interest in old transport aircraft and their systems. I hope my comments about the Nav's work on 133s was technically accurate. I used Loran A myself in commercial fishing back in the day, mostly old APN 9s and even a few APN 4s. I also did celestial nav, mostly just noon sun shots but some star work too. I like navigation, which is a disappearing art now with cheap GPS on the scene.
Your blog was very hard to find for some reason, but glad to know it is there.
Man what an aircraft. I was knocked out by its size. Astounding that one was flying in 2008 without a giant maintenance and logistics org behind it.

Also, Mark's web site is fascinating. Lots of "airplane stuff" from a sky-diver's perspective: http://boeing377.googlepages.com/skydive2
