"1951, Utah, USA — On the Measured 13 Mile Straight-a-way Course, Bonneville Salt Flats, Utah. Roland R. Free, Making a New American Motor-Cycle Record. Roland R. Free, of Los Angeles, Calif., riding a British-Vincent Motor-Cycle in a prone position to cut down wind resistance approximately 2 miles, on Sept. 11, 1950, established a new American speed record for 1 mile @ 156.71 miles per hour. Mr. Free’s picture was taken from an automobile running parallel to the black line while traveling in excess of 100 M.P.H. just before the auto reached the measured 1 mile zone of the 13 mile straight-a-way course, Mr. Free caught up with the automobile and immediately after his picture was taken, he gave his Motor-Cycle the gun; the photographers say it seemed like they were still, the way he left them with his sudden burst of speed. — Image by © Lake County Museum"
