The letter to Adamski was signed by the fictional "R.E. Straith", a representative of the non-existent "Cultural Exchange Committee" of the U.S. State Department. Straith wrote that the government knew that Adamski had actually spoken to extraterrestrials in a California desert in 1952, and that the department also had its own evidence bearing out his claims. It encouraged him to continue his work of communicating his experiences to the public, since the government could not take an official position on the matter.
