This F-86 aircraft is being lowered into the 40 x 80 Foot Full Scale Wind Tunnel at the NACA Ames Aeronautical Laboratory, Moffett Field California. Behind the aircraft and out of view, a crane operator lowers the jet as a mechanic holds a guide rope aligning the F-86 with supporting struts located down in the tunnel. Once the jet is mounted on the struts, tunnel doors visible on either side of the aircraft's wings will close to form an air tight seal.
