I discuss with author and researcher Hazel Stuart on the legend and the real  Robert Kirk, Kirk engaging the phenomena and then passing the baton to future researchers and investigators.  Hazel has researched Kirk for well over a decade and is currently writing a book on his life times, Hazel has some great insights on his work and life.
