When the Armistice was declared, ending World War I, Goddard was transferred to Carlstrom Field, Arcadia, Florida, where he finally graduated from flying school and was rated a pilot in May 1919. At the personal urging of General Billy Mitchell, who was impressed with Goddard's camera experimentation, he was assigned to McCook Field, Ohio, as officer in charge of aerial photographic research. In that capacity, he started developments in the infra-red and long-range photography, special aerial cameras, photographic aircraft and portable field laboratory equipment and formed the nucleus of the Photographic Laboratory at Wright-Patterson Air Force Base, Ohio.
