Restoration and preservation of our collection is conducted in the Mary Baker Engen Restoration Hangar. The facility is spacious enough to accommodate several aircraft at one time, giving our restoration specialists the room and equipment required to reconstruct, repair, and preserve artifacts. The Restoration Hangar also houses numerous support shops where Museum staff complete the many highly specialized functions necessary to preserve the collection. From a glassed-in mezzanine, you can view restoration projects in progress.
