Dr Robert Sarbacher was a consultant to the Research and Development Board.
In an alleged conversation with Wilbert Smith, Smith recorded the following:
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.
He died in 1986
