ECN-4242 In this 1974 NASA Flight Research Center photograph, a Boeing B-747 jetliner is shown taking part in the trailing wake vortex study. In the photograph, the two wing tip vortex trails, being the strongest, stay in tight cylindrical rolls. The ''strength'' of the vortices decreases toward the midspan of each wing, and the trails become less defined. September 20, 1974 NASA Photo / NASA B-747 Project Description
