Paul R. Hill (1909-1990) was a renowned NASA engineer and UFO enthusiast. He received his B.S. in mechanical engineering from University of California, Berkeley in 1936. After teaching at the Polytechnic College of Engineering in Oakland, California, Hill began his career with the National Advisory Committee of Aeronautics (NACA) in 1939, which became the National Aeronautics and Space Administration (NASA) in 1958. He worked at NASA until 1970, where he published numerous scientific and technical reports. Hill was also an adamant UFO enthusiast. Based on his own personal sightings in 1952, Mr. Hill tried to use his scientific and engineering knowledge to understand how UFOs worked and eventually built his own flying platform. His book on the topic, Unconventional Flying Objects: A Scientific Analysis, was published post-humously in 1995. Mr. Hill was married to Frances Hoback Hill (d. 1999) and had one daughter, Julie M. Hill. Hill died in 1990 at the age of 81. (Synopsis of_UFOs_JSE_Review by puthoff.pdf)
