Rewards have been issued to APR Patreon patrons for April, 2018. This month, the “Diagram” is a Sikorsky lithograph of a Heavy Lift Helicopter concept. The Documents include a US Army catalog of airborne weaponry; a paper describing possible additional missions for the Saturn launch vehicles, and BOAC brochure extolling the virtues of the Comet 4 jetliner. The CAD diagram is of the British Interplanetary Society’s “Deadalus” starship design.
If you are interested in helping to preserve (and get copies of) this sort of thing, consider signing up for the APR Patreon.
