During his nearly 12 years with NASA he was responsible for several major aeronautical research programs, including those involving the highly successful rocket-powered X-15, the supersonic XB-70, the fleet of wingless lifting bodies that contributed to development of the Space Shuttles, and the Lunar Landing Research Vehicle that paved the way for successful landings by Apollo astronauts on the moon’s surface.

Paul earned a Bachelor’s degree in aeronautical engineering from the University of Detroit in 1939. He first worked for Taylorcraft Aviation Corporation in Ohio before beginning his government service career in 1940 at Wright Field, Ohio. In his first 20 years of civilian service in aeronautical engineering, he was author of more than 40 technical publications.

Bikle was a veteran of 23 years of soaring. He established two world soaring records on February 25, 1961, achieving an altitude of 46,269 feet and a total-altitude-gained mark of 42,305 feet. Both marks were certified by the Soaring Society of America, National Aeronautic Association, and the Fédération Aeronautique Internationale. Bikle held those records for sailplanes for more than 20 years.

In July, 1962, Paul was awarded the NASA Medal for Outstanding Leadership. NASA cited him for his part in directing the successful X-15 flight operations and research activities. Paul was also a Fellow in the American Institute of Aeronautics and Astronautics.

Bikle was born June 5, 1916, in Wilkensburg, Pennsylvania; he died January 19, 1991, in Salinas, California.
