National Archives and Records Administration (RG 342-C, Records of U.S. Army Air Force Commands, Activities, and Organizations)
Photograph from a series held by the National Archives on the first African American Airborne unit, the 555th Parachute Infantry Battalion, also known as the Triple Nickle. This image was scanned by the National Archives at College Park, Maryland. Their description reads: "'Operation Fire Fly'. A paratrooper in a tree is a common sight near a fire. The troopers of the 55th Parachute Infantry prefer to land in trees rather than on the rough terrain. They carry 150 feet ropes with them to aid in descending. Oregon." This is likely part of a training jump in the Umatilla National Forest.
There are no know restrictions.
