Here are photos of portions of a few documents I’m considering as Patreon rewards. These have not yet been scanned in; some will require a bit of effort to make them presentable, but all are pretty interesting in my view. If I understand the Patreon system correctly, the system debits the credit cards or PayPal accounts of those who have pledged at the “end of the month ” (any day now, I expect), and the rewards will be distributed a few days later – when I have them ready – to those who have been successfully charged. The upshot is that if you buy in the day *after* billing, you don’t get the rewards for this month, but only *next* month. So you miss out on the first batch. The $100 benchmark is safely in the past, and there seems to be a slow creep towards the $200 benchmark, which will mean two uploads as rewards for the first month is feasible. In the event that the contribution level gets there, I’ll try to have one large format drawing and one document per month, so long as that’s practical.

So if you don’t want to miss anything, sign up soon!

A NASA report from 1972 showing a *lot* of designs for Space Shuttle concepts. Includes designs that clearly foreshadowed the Shuttle as actually built, as well as some really wacky ones.

Two official aircraft recognition guides from the early 1950s to help ground observers tell friendlies from potential bandits.

A Convair report from 1948 on an assault seaplane. Includes a *lot* of excessively detailed design diagrams. This one might have to be broken up into several parts due to the size of it.

A report on the Regulus II missile which includes detailed diagrams of both the tactical missile version and the reusable test flight version. Some really snazzy large foldouts, which will require a bit of work to clean up.
