SMITH: ...I have read Scully's book on the saucers and would like to know how much of it is true. SARBACHER: The facts reported in the book are substantially correct. SMITH: Then the saucers do exist ? SARBACHER: Yes: they exist. SMITH: Do they operate as Scully suggests on magnetic principles? SARBACHER: We have not been able to duplicate their performance. SMITH: Do they come from some other planet? SARBACHER: All we know is, we didn't make them, and it's pretty certain they didn't originate on Earth. SMITH: I understand the whole subject is classified. SARBACHER: Yes, it is classified two points higher even than the H-bomb. In fact it is the most highly classified subject in the US Government at the present time. SMITH: May I ask the reason for the classification ? SARBACHER: You may ask, but I can't tell you.
