NASA technician W.L. Jones inspects a transport model Pathfinder I between test runs at Langley's National Transonic Facility (NTF). The stainless steel model is representative of the next generation of subsonic transports. With the help of super-cold nitrogen and high pressure, the NTF is the first major wind tunnel that can simulate full scale aerodynamic flight conditions.
A technician mounts a model of the Apollo Launch Escape System (LES) in the Unitary Wind Tunnel at the NASA Ames Research Center, Moffett Field, California. The LES was a tower like structure consisting of four solid propellent motors mounted atop the Apollo Command Module. In the event of a contingency, (booster failure or some other imminent failure) the LES would be commanded to ignite, subsequently removing the Command Module from the Saturn launch vehicle.
