In 1936, Parsons along with his colleagues Edward Foreman and Frank Malina initially appear to experience a day of failed rocket launches.  Before attempting one last launch, Parsons decides to cast a spell on the rocket, much to the understandable skepticism of Foreman and Malina. The rocket makes it about a 100 feet up before blowing up but in the explosion, Parsons claims to once again see a woman in red. During this time Parsons becomes a believer in the Thelema Church and even wrote numerous letters to its leader, Aleister Crowley.
