Adamski took great pride in the Straith letter. He publicized its contents, and UFO proponents all over the world used it to validate their claims. When FBI agents investigated it, they informed Adamski that the Straith letter was a hoax and asked him to stop using it as evidence in support of his claims, but Adamski refused and he continued to display the letter in his lectures and talks. FBI agents also questioned Barker about the matter, but no criminal charges were filed.
