A few more items I’ve recently paid for that will appear on the APR Patreon/Monthly Historical Documents Program catalog:
1) General Dynamics report “Technical Proposal for Advanced Exhaust Nozzle System Concepts,” 1977 designs for advanced fighters
2) “NASA Aeronautics,” 1974
3) NASA Facts – “The Jupiter Pioneers”
4) “Cessna EV-37E STOL” report, 1964
5) Cessna 407A: report on the proposed but unbuilt 407A transport derivative of the T-37
6) Cessna AT-37E STOL: report on attack variant
7) Cessna YAT-37D counter-insurgency airplane report
Also purchased were a large number of vintage “Space World,” “Aviation News” and “Interavia” magazines for research and “Extras” purposes.
If you would like to help fund the acquisition and preservation of such things, along with getting high quality scans for yourself, please consider signing on either for the APR Patreon or the APR Monthly Historical Documents Program. Back issues are available for purchase by patrons and subscribers.
