The exterior of Hughes Research Laboratories where rock bits were test-drilled in Culver City, California in the 1940s. Transcribed from note taped to back of photo: "Rock bits are test-drilled in the laboratory under conditions that duplicate, as far as is possible in the laboratory, those encountered in actual drilling. As a result, rotational speeds, loads, and fluid volume are closely controlled. The rig operator occupies a splash-proof booth above the 'cellar floor.' The instruments on his control panel provide for application and measurement of variable axial loading on the drilling bit up to 100,000 lbs., variable rotational speeds up to 400 rpm, measurement of bit penetration over a total vertical travel of 5 feet at rates up to 180 ft. per hour, and torque. On the panel, also, are several controls for the operation of mud pump and other accessory equipment."

Typed on a piece of paper attached to the image: "Hughes flies to New York for hop to Paris. L to R L. Tom Thurlow and Harry Connor, Hughes, Richard Stoddart and Dale Powers. 7/4/1938."
The black and white view of a crowd of people, possibly including reporters and members of the press, standing atop a tower as they wait for the arrival of Howard Hughes in his Lockheed 14 aircraft at Floyd Bennett Airport, New York. This final landing for Hughes marked the end of his Round The World flight.
