'Navy Mystery Plane'. This is the prototype of the PBY Catalina. It had just flown non-stop from Coco Solo, Panama to San Francisco in 34 hours and 45 minutes. The aircraft underwent modifications over the winter and became the XPBY-1 as the P3Y was redesignated PBY. The building in the background belongs to the old Alameda Airport, just to the east of the new Naval Air Station Alameda which opened in 1940. Photo from: San Francisco Examiner / UC Berkeley Library
