Jack Parsons, L Ron Hubbard and The Babylon Working Ritual - a powerful ritual used to open a portal into another realm. 

This ritual is used by occultists and demonologists to summon and control spirits. In 1946, Jack Parsons of JPL and L Ron Hubbard did this ritual and something came through to our dimension.
