Dr. Robert H. Goddard's rocket is in the tower, ready for the July 17, 1929, test at Auburn, Massachusetts. This was the fourth flight of a liquid-propellant rocket. Rocks were piled on pipes directly under the nozzle, on a frame suspended from the two 3/8 inch pipe guides to keep the latter as straight as possible by the tension produced in this way. The noise from this particular rocket launch attracted the attention of the entire community. When the public grew concerned over the potential hazards of the rockets, Goddard was forced to conduct his test flights on the Army artillery range at Camp Devens, Massachusetts.
