F-104 NASA 734

The Air Force lent the NACA Starfighter, serial number 56-734, in October 1957. Neil Armstrong flew it on January 14, 1958, Milt Thomson flew it May 28, 1959.
With NACA followed a major program to obtain boundary-layer-transition measurements in full-scale flight on this aircraft (NACA HSFS (High Speed Flight Station) program, Dryden). To obtain the desired data, HSFS personnel installed pressure instrumentation and temperature gauges on the outside surface of the left-hand wing. The leading edge flaps were deactivated and a fiberglass glove installed to maintain the original contour and smooth surface of the wing.
"NASA 734" (FG-734/6734) was transferred back to the USAF on January 10, 1961
