Transcribed from attached press release: "HUGHES ROCK BIT TEST In a block-long laboratory at Houston, Texas, the Hughes Tool Company can simulate oil drilling conditions anywhere in the world. Here a Hughes bit is tested on a hard formation. Howard Hughes' father invented the rock bit in 1908 and the resulting business became the cornerstone on which Howard Hughes built his fabulous industrial empire in motion pictures, air transportation, aeronautical research and design, aircraft manufacture, electronics, armament and brewing."
