Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.

General Doolittle has called the ship the best military plane in existence." 4x5 Kodachrome transparency by Alfred Palmer, Office of War Information. View full size.
