The San Diego Air & Space Museum is loaded with great images from aeronautical history. The breadth of the collection is amazing with images from the earliest days of flight, historic planes and pilots, space travel, and everything in between.

For their launch into the collection the museum has uploaded their The Ryan Aeronautical Photo Collection, “These rare images document the history of San Diego’s Ryan Aeronautical. Highlights include the Spirit of St. Louis, Charles Lindbergh, the ST series of aircraft, PT series and Brougham series of aircraft, the Firebee and Fireball, among other subjects!“

The key goals of The Commons on Flickr are to firstly show you hidden treasures in the world’s public photography archives and secondly to show how your input and knowledge can help make these collections even richer. You’re invited to help describe the photographs you discover in The Commons on Flickr, either by adding tags or leaving comments.
