Transcribed from attached press release: HUGHES TOOL COMPANY Cornerstone of the industrial empire of Howard Hughes is the Hughes Tool Company of Houston, Texas, which last year produced more than half a million rock bits for drilling the kind of deep wells now producing 90 per cent of the world's petroleum. In the company's mechanical testing section (above) engineers test the products under conditions simulating actual drilling. Howard Hughes' father's invention of the rock bit is believed to be one of the most important industrial developments of the century; without such a tool we might still be living in a horse and buggy era."
