Retromechanix is scanning, restoring and publishing rare aerospace photos, illustrations and documents covering lesser known American aircraft from the first half of the 20th century, such as forgotten prototypes and secret projects which remained on the drawing board. These documents originate from various US government repositories, such as The National Archives, The Naval History and Heritage Command, The Air Force Historical Research Agency, and other institutions. We believe that the bulk of the collection has not been published before.

Every month, we are uploading at least 100 pages of material in PDF format. Previews of these documents can be viewed here on our Youtube channel. Patreon subscribers may choose to download the documents with photos and drawings reproduced at 150 dpi or 300 dpi, depending upon your subscription tier. By the end of the project, we estimate that subscribers will have access to an archive of over 20,000 pages of primary documents shedding light on secret aircraft projects, prototypes, and lesser known aspects of US aerospace history.
