I have made available for APR Patrons the following:
1) “Titan III B-C-D-E Propulsion Handbook,” from Aerojet, explaing and diagramming just about everything you want to know about the Titan III propulsion systems, from the SRMs to the Transstage. I originally got this via ebay.
(This shows just a small portion of the ~300 page handbook)
2) “Aircraft Descriptive Data for Northrop F-89F.” A collection of then-current data on the projected (and unbuilt) F-89F. This was from a collection gathered by Lockheed to keep tabs on their competitors. Has some “Secret” markings on it. I originally got this via ebay.
3) Skylab diagram. This very large format illustration was found in the NASA HQ and photographed piecemeal and painstakingly reassembled, using text scanned from another copy of the illustration (with a far smaller diagram, but good text).
4) An original layout diagram of the XB-70. It took several years to get this diagram into this shape. It seems pretty good to me.
You can gain access to these by becoming an APR Patron for as little as $1.50 a month. That’s not so very much, is it? Check out the APR Patreon page for more details.
