The admission entitles visitors to explore the main Museum and adjacent Gallery and receive a guided tour of the airplanes in the flight line at Strawberry Point. On certain days the Restoration Gallery is also available to visitors over 18 years old.

Between the years 1909 and 1960, The Glenn L. Martin Company produced over 80 different types of aircraft totalling more than 11,000 planes, including dozens of Boeing B-29s (50 of which were the "Atomic Bombers" including Enola Gay and Bockscar). Beginning in the 1950s, the company ventured into missiles, space and electronics and, since the Lockheed merger in 1995, has now reestablished itself as a prominent aerospace manufacturer.

Moving from Los Angeles to Cleveland and then to Baltimore in 1928, Glenn Martin bought over 1,260 acres in the Baltimore suburb of Middle River and built some of the most modern aircraft manufacturing plants of its time. Huge facilities sprang up including an airport (with hangars and terminal) and several communities that still exist.

The Museum's purpose is to maintain an educational institution dedicated to the promotion, preservation, and documentation of aviation and space history in Maryland, namely, the contributions of Glenn L. Martin and his successful company. Operated by dedicated volunteers, the Museum is active in the cultural life of surrounding communities and has begun to extend its activities state-wide. The Museum is certified by the U.S. Navy and Army. All funds required for the acquisition, restoration, maintenance, and display of museum material are derived from individual and corporate donations. Members of the Museum share a desire to preserve aviation history and we welcome all those who share the same interests.

Home to the world's oldest airport, three major aircraft manufacturers and many smaller ones, the first commuter airline, and countless other aviation innovations, Maryland has a rich aviation and space heritage in danger of loss (see information on the new museum initiative).

The Museum has collected over a dozen aircraft, thousands of reels of motion picture films, plans, documents, research models, aircraft tools, and components; and a gigantic indexed collection of more than 200,000 aviation and company photographs. These archives have supported documentary films and numerous publications. Without the efforts of the Museum, these research materials would not be available to the public; many of the collection's artifacts would have been destroyed. But much remains to be preserved and the collection is growing.
