Liberator over the Grand Canyon. This behemoth of the air today, light bomber by tomorrow: standards, is built around Davis wing, which is very thin, is made possible because of multi-spar construction. The rapier-thinness of the wings reportedly gives 25% less drag at normal speeds and 10% less drag at high speeds. Service ceiling is 36,000'.
