Recently uploaded into the APR Extras Dropbox folder for 2017-12 were a number of diagrams of United States Air Force rescue boats. Some of them were surprisingly large, given that the USAF is, you know, not about boats.
If you are interested in helping to preserve this sort of thing, as well as gaining access to the complete set of high-rez scans, consider signing up for the APR Patreon.
