On August 24, both MacArthur and Kenney arrived at Port Moresby to be present for the final stages of the planning and for the execution of the operation. This photo well illustrates how Lt. Col. John J. Tolson III became known as "Smiling Jack." Tolson stayed in the military,  commanded the First Cavalry Division (Airmobile) in Vietnam, and virually wrote the book on the use of helicopters as a leading instrument of modern warfare. He retired as a Lieut. General and died in 1991, aged 76.
