On 31 July 1999, physicist Hal Puthoff emailed former CIA physician Kit Green and Green's partner, engineer Kristin Zimmerman, asking whether Green had read a set of UFO Magazine articles about crash retrievals by a group called "Zodiac", and whether he had ever heard the name.[1]
The articles

Three articles by "Greg Halifax" appeared in UFO Magazine in 1998, in the May/June, September and December issues. They told the story of "Sedge Masters", a man recruited by the CIA and briefed at Wright-Patterson Air Force Base about two craft recovered at Roswell in 1947. In the story, Zodiac was the usual code name for the MJ-12 group and program, said to have recovered eleven more craft by the early 1980s. The magazine's editor warned that the material was largely unverified.[1]
The email

Puthoff wrote that he had reason to believe the articles were only lightly fictionalised versions of a source's experience writing up records for the archives at Wright-Patterson, and that Zodiac was supposed to be a true name. No reply from Green appears in the surviving thread.[1]
How it became public

The email was part of a thread attached to a memo from physicist Eric Davis to Robert Bigelow dated 23 March 2001, which surfaced online in 2019. The memo itself concerned Green's views on the "alien autopsy" film, which Green later said were mistaken.[1][2]
Later history
Davis went on to look for a former TRW employee said to have worked on Zodiac. Researcher Richard Dolan later said the Halifax articles were written as fiction and that their author was probably a corporate lawyer for TRW. No document has confirmed that a program called Zodiac existed.[1]
