Jackson, Air Research and Development Headquarters, Baltimore; Gale J. Moore, Pilot; possibly Chal Bowen, Flight Engineer/Co-pilot, and an unidentified man, October 23, 1952.

Wing and engines of the Flying Boat are visible in this photograph that was taken during Howard Hughes first test flight. Harbor Island is visible in the distance. Photograph likely taken from inside the plane. Stamped on the back of the photo "Hughes Aircraft Photo" and the date "Nov 2 1947." Los Angeles Harbor is now known as Long Beach Harbor.

Transcribed from attached press release: "DRILLING LABORATORY The fundamental purpose of all Hughes rock bit research is to improve bit performance. In attaining this improvement it is necessary to balance design with the application of correct metallurgical materials and manufacturing methods. The preliminary proving ground is the Drilling laboratory housed in the main Laboratory building. Its field-size drilling rig, with 118 ft. derrick, was especially designed to test rock bits in a manner simulating oilfield drilling conditions."

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, Terminal Island are now known as Long Beach.

Men and women in the Hughes Laboratory Machine Shop are devoted to the building of full-scale test models of rock bits, tool joints and other drilling tools for laboratory and field testing. In connection with the latter, the shop is equipped to manufacture these tools in sufficient quantities to make possible extensive and simultaneous field trials. The machine shop handles a large amount of work for Research, Product and Metallurgical Engineering divisions. This includes building new designs, new mechanisms and new devices for preliminary testing.
