Press release attached to back of photo: "LAUNCHING WORLD'S LARGEST PLANE The Hughes Flying boat was launched for the first time November 1, 1947. After the three concrete docks, one containing the hull and two the wing pontoons, were pumped with sea water to the outside level, gates were lowered and the Flying Boat was carefully towed forward by tractors, and by boats as the tail cleared the dock. During taxi tests the following day Howard Hughes made a surprise flight of a mile." Stamped on back of photo: "Hughes Aircraft Photo" and the date "Nov 1 1947." Los Angeles Harbor is now known as Long Beach.
