During the past year, the Mars aircraft has become a familiar figure to travellers passing over the Golden Gate bridge. Before being returned to Patuxent, she flew thousands of tons of cargo, including vital medical supplies to Honolulu where the cargo was transferred and sped to the war zones. Album from The Glenn L. Martin Company, Baltimore, Maryland, 1941

Seventy tons of fighting strength were added to the Navy air force when Mars, the largest ship ever to fly, was completed. A Martin-built plane, it has four 2,000 horsepower motors, a hull the size of a 15-room house, and a wing-expansion equivalent to the height of a 20-story building. Mars can fly non-stop to Europe and back. Office of War Information photograph. Courtesy of the Library of Congress.
