Here’s something I have some vague recollection of posting before, but couldn’t find after a cursory search: a sketch of the seating arrangement of a 3-man A-4 rocket (might be the A-8 derivative). This is a scan of a photocopy of a photocopy; the original photocopy was found in the files of a researcher at the NASM twenty or so years ago. It’s thought that the sketch was originally made by Werner von Braun during WWII.
Little data is provided; range is given as 500 km. *Presumably* this would have been a winged, landing-gear-equipped derivative of the A-4; replacing the warhead of the V-2 with just three guys seems like a waste of three guys, as well as a not terribly effective weapons system.
The full-rez scan (such as it is) has been made available to APR Patrons in the 2015-12 APR Extras Dropbox folder. If you’d like to help out and gain access to this and many other pieces of aerospace history, please check out the APR Patreon.
