It educates visitors through the use of exhibits, artifacts, archival materials and stories about aviation in Maryland over the last hundred years, with an emphasis on the Glenn L. Martin Company and the more recent Lockheed Martin histories. The aircraft currently on display are on loan from the Navy and Army, with the exception of the Martin 4-0-4, which was donated to the museum in 1999. The museum also hosts periodic open cockpit days featuring three or four selected aircraft. The history of the Martin Corporation is told with displays of models, films, photographs and documents from the museum's large archive. There is a research library, through which this archive can be examined on appointment. The museum relies on volunteers who run the museum and assist the visitors with admissions, store purchases, and tours. They also help with visiting school groups, other educational projects and aircraft restorations."@en . . "9339"^^ . . . . . . . . "Glenn L. Martin Maryland Aviation Museum"@en . .
