Looking at the Radio Mysterioso site, I found an ad for this book: Sex and Rockets: The Occult World of Jack Parsons, by John Carter, with an introduction by Robert Anton Wilson. Seems like another book to add to my long list of books!
So who was Jack Parsons, I asked myself. An extremely interesting person! From Wikipedia:
John Whiteside Parsons (born Marvel Whiteside Parsons on October 2, 1914 – died June 17, 1952), was an American rocket propulsion researcher at the California Institute of Technology and co-founder of the Jet Propulsion Laboratory (JPL) and Aerojet Corporation. He was also an enthusiastic occultist, and one of the earliest American devotees of Aleister Crowley.
Parsons was also an avid practitioner of the occult arts, and a follower of Thelema. He saw no contradiction between his scientific and magical pursuits: before each rocket test launch, Parsons would invoke the god Pan.
There's more, much more . . . definitely an intriguing person in the world of the strange!
