several permanent galleries, including the Home Front, Planning for D-Day, and the D-Day Beaches. The third floor of the Louisiana Memorial Pavilion includes an observation deck for closer viewing of the hanging aircraft. In January 2013, the museum opened the US Freedom Pavilion: The Boeing Center, which is the now largest building on the campus. The collection in the US Freedom Pavilion includes a B-17E Flying Fortress bomber, a B-25J Mitchell bomber, an SBD-3 Dauntless, a TBF Avenger, a P-51D Mustang, Corsair F4U-4 and an interactive submarine experience based on the final mission of the USS Tang. The B-17E is the airplane dubbed My Gal Sal, famous for having been lost over Greenland and recovered 53 years later. The US Freedom Pavilion was paid for with a $15 million donation from the Boeing Company and with a $20 million grant from the US Department of Defense with congressional approval. In December 2014, the museum opened the Road to Berlin portion of the Campaigns of Courage pavilion, focusing on the European theater of war. A Messerschmitt Bf 109 hangs in the building. The Road to Tokyo portion of this same pavilion, which focuses on the Pacific war, opened in 2015. The entire pavilion, including both galleries, measures 32,000 square feet. In June 2017, a new exhibit, The Arsenal of Democracy, opened in the Louisiana Memorial Pavilion, dealing the experience on the Home Front. The museum also has plans to open what will be called the Liberation Pavilion by 2020 with assistance from the Monuments Men Foundation for the Preservation of Art. Its goal would be to explore the "joys, costs, and meaning of liberation and freedom," as well as how the legacy of World War II affects us today. The museum part of the Monuments Men and Women Museum Network, launched in 2021 by the Monuments Men Foundation for the Preservation of Art. Visitors to the museum are encouraged to allocate roughly 2½ to 3 hours to tour the museum. An award-winning 4-D film, Beyond All Boundaries, is shown in the Solomon Victory Theater and gives the visitor an overview of the war on every front. Other multimedia displays are integrated into most of the museum's exhibits, notably the dozens of video oral histories conducted with veterans of the war by museum staff. The museum currently houses two restaurants, the American Sector Restaurant & Bar and the Soda Shop. The museum
