Project 9.1 was organized to document the cloudrise phenomena during Operation Castle by means of photographs exposed from aircraft. This supplements Program 13.2, a Los Alamos Scientific Laboratory study of the early cloud-rise by means of ground-based cameras. Four aircraft were used: One RB-36 operating at 40,000 feet, and three C-54's working at 10,000 to 14,000 feet. The planes were 40 to 100 miles from ground zero, usually at the 50-mile range at H-hour. Aerial cameras were installed on A-28 Stabilized Mounts and operated by the Lookout Mountain Laboratory, U.S. Air Force. Photographs were taken of the visible cloud, from several directions, as a function of time. Supporting data were photographed automatically, and the aircraft furnished navigation logs to document their position at every instant. The data obtained are more complete and more accurate than any obtained during previous operations. (Author)
