Yet another one I've put on Ebay:
"Integral Launch and Reentry Vehicle System First Interim Technical Review Briefing, Vol. 1" Convair Division, General Dynamics Corporation, report GDC-DCB69-012, dated 29 April 1969. This report is loaded with drawings of possible vehicles, from small lifting bodies atop conventional boosters to large fully-reusable flyback boosters with advanced manend shuttle-like upper stages, The ILRV program was an immediate predecessor to the Space Shuttle program, and was nowhere near ready to come to a specific design... thus, a wide variety of concepts were studied. This copy of the report is incomplete, but presents all the illustrations.http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250138333705
This one has some damned spiffy drawings of various space launch options, from the mundane to manned flyback twin-F-1-engiens flyback boosters. A number of detaield drawings of the Convair "Triamese" vehicle, which had three aerodynamically identical vehicles... two boosters, one orrbiter.
