Calling All Earthlings

Summary: A 1950's Howard Hughes employee-confidante, George Van Tassel, uses alien guidance and Nikola Tesla's ideas to build a time machine -- The Integratron. Is he deluded, or could it actually work? As waves of devotees join him in the California desert, the FBI gets involved fearing insurrection and possibly more. Nearing completion, Van Tassel's tale and the Integratron meet an unexpected end: the "workings" of the dome finally emerge. The unusual story is told by historians, astronomers and current residents of Joshua Tree, including the stewards of the Integratron, the Karl Sisters, and a galaxy of believers and skeptics alike.
