Rush Work For First Flight Of B-19 -- The B-19, greatest airplane ever built by man, is shown as mechanics go over it these days to make it mechanically perfect for the first test flight, which will take place in several weeks. The rounded nose, mostly built of glass, is pictured above. The front wheel of the tricycle landing gear is almost as big as a man. The B-19 could take off with a full load of bombs, fly to Europe and then back to New York without a stop. June 6, 1941. (Photo by International News Photos).
