We currently have about 5.000 aviation documents in our archives. Some of these documents are from 1920s, while some are from late 1970s. aeroengineer.net's aim is to publish all of these historical documents on world wide web. Some of these documents might not be interesting for every aviation enthusiast. However, even a magazine advertisement of 1930s can be very interesting for some of the aviation fans. For this reason, we intend to publish everything we have, valuable or not valuable.
