This is somewhat ironic, seeing as David Miscaviage is himself a High school dropout, who employs Hubbard quotes such as "unkillability" in actual speeches to his congregation (try invulnerability, invincibility, immortality; Dave, anything else, please) and nothing much is taught to children of staffers inside the Church except for the pseudo-scientific ramblings of Hubbard, who thought that knocking together two pieces of plutonium could produce a nuclear explosion (wow, the ignorance)
