In the book
The Creation of Human Ability, Hubbard describes two training "Routes", with the exercises in Route 1 numbered R1-4 to R1-15, and the exercises in Route 2 numbered R2-16 to R2-75. R2-45 is simply described as "an enormously effective process for exteriorization but its use is frowned upon by this society at this time". George Malko gives a slightly different account in his 1970 book
Scientology: The Now Religion, writing that "Hubbard is said to have marched out onto center stage at one of the Scientology congresses in Washington, D.C., in the late fifties, pulled out a .45 loaded with blanks, fired it into the audience, and announced to the stunned assemblage, 'I just thought you'd like to see what R2-45 looks like!'" A 2007 promotional film produced by the Church of Scientology features a claimed eyewitness account of Hubbard's introduction of R2-45. According to an unnamed veteran Scientologist who appeared in the film, R2-45 first appeared in a 1954 lecture given by Hubbard in
Phoenix, Arizona, in which he described a series of auditing processes in numerical order: Decades later, Hubbard's estranged son
Ronald DeWolf said that he had been present at a meeting where his father fired a pistol into the floor to illustrate R2-45. DeWolf commented, "I thought he was kidding and that it was a blank, but it wasn't; there was a hole in the floor. It was for real; he meant it." ==R2-45 in Hubbard's lectures==
