The San Diego Air & Space Museum's Mitsubishi A6M7 Zero.

The San Diego Air & Space Museum’s world-class Restoration Facility has recently been in the spotlight, thanks to renewed opportunities for visitors to tour its basement-level workspace at the Balboa Park location. Since the Museum’s founding, a team of skilled staff and volunteers has meticulously restored and recreated historic aircraft and engines at the Facility. Visitors can also explore the Museum’s dedicated restoration hangar at Gillespie Field, which also is integral in our aircraft and artifact restoration efforts.

While visitors touring the Restoration Facility witness the remarkable craftsmanship that brings aviation history back to life, the San Diego Air & Space Museum’s Library & Archives play an equally vital role behind the scenes. The Library & Archives preserve the documentary and photographic records that make authentic restoration possible, document the Museum’s collections, and safeguard the stories and technical knowledge behind every artifact for future generations.

Each aircraft in the collection is typically accompanied by logbooks, technical drawings, photographs, correspondence, engineering records, manuals, research files, provenance documentation, and maintenance records, which provide the foundation restorers rely on to understand how each aircraft was originally built, modified, and operated. In addition, the history of every aircraft in the collection, along with detailed documentation of its restoration process, is recorded and preserved in the Museum’s archives, ensuring that both the craftsmanship and the story are never lost.

A prime example of a complete archival collection is that of SDASM’s Mitsubishi A6M7 Zero. The collection has technical manuals, engineering specifications, cockpit and armament documentation, painting and marking information, restoration records, and extensive correspondence between Museum staff, restorers, and international experts. Many documents are original Japanese-language manuals and technical papers that highlight the global research necessary for authentic restoration. Photographs of the Zero from the collection document the restoration process and how it appeared in past Museum exhibits and are free to view on our Flickr page. These images serve as both a historical record of the restoration itself and an invaluable resource for future restorers, historians, students, modelers, and aviation enthusiasts.

Today, these archival collections support researchers worldwide while ensuring that the knowledge gained from each restoration project is preserved for future generations. Every restoration not only returns an aircraft to the public; it also creates a new historical record that becomes part of the Museum’s permanent archives.
