View of two Boeing B-17 Flying Fortress bombers. Three men stand on runway. Label on back: "A familiar sight at the Boeing Aircraft Co. in Seattle as a new Boeing B-17E Flying Fortress roars overhead on a delivery flight to an Air Forces base. The other Fortress in the foreground awaits a final check flight. Powered by four turbo-supercharged Wright engines, the B-17E boasts many refinements over earlier Flying Fortresses." Handwritten on back: " Aircraft in action."
