Dr. Marc Feix: Dr. Marc Feix was a French nuclear scientist who worked a few years at Langley during the mid-1960s. "Feix was nominally assigned to Robert Hess's Plasma Physics Section, but he actually worked with various people throughout the branch." James Hansen stated: "Most notable of [the new research fields] was magnetoplasmadynamics (MPD)--a genuine product of the space age and an esoteric field of scientific research for an engineering- and applications-oriented place like Langley. If any "mad scientist" were working at Langley in the 1960s, they were the plasma physicists, nuclear fusion enthusiasts, and space-phenomena researchers found in the intense and, for a while, rather glamourous little group investigating MPD. No group of researchers in NASA moved farther away from classical aerodynamics or from the NACA's traditional focus on the problems of airplanes winging their way through the clouds than those involved with MPD."
