The Day After Roswell

The Day After Roswell (Pocket Books, 1997) is the document in which the Corso claim enters the world. Written by Philip J. Corso with William J. Birnes, it asserts that Corso ran an Army Foreign Technology desk under Arthur G. Trudeau and was given custody of material recovered at the UFO crash at Roswell, which he then seeded to defence contractors [S1].

Its importance to this graph is provenance, not content: no attributable telling of the story predates it. Karl T. Pflock met Corso in January 1993 and recorded only an impression of the man, not a claim. The book was promoted via Dateline NBC on 24 June 1997 and Art Bell's Coast to Coast AM on 23 July 1997 [S1]. Thirty-six years of silence, then a book.

It began as something else

Birnes ghostwrote the manuscript, credited as co-author, working with Corso for roughly two years. The project started as a conventional military memoir and pivoted to UFOs only after Corso raised the topic in conversation [S1].

The pitch materials corroborate that pivot from the outside. Strom Thurmond's office states the senator was approached about a memoir titled I Walked With Giants, accompanied by a 21-page outline that contained no aliens [S2]. Thurmond supplied a foreword on that understanding, then publicly disavowed the book on publication. Simon & Schuster apologised and removed the foreword from subsequent editions — a change visible in the citation practice of contemporaneous reviewers, who by early 1998 were referencing "the edition of Corso's book minus the now withdrawn foreword" [S3][S4].

Factual errors identified on publication

Critics within UFO research, not outside it, catalogued impossibilities in the narrative:

• CIA headquarters at Langley was not open for business in May 1961, when the book stages a confrontation there; Frank Wisner, the antagonist of that scene, died by shotgun on his Maryland farm in October 1965, not by hanging in a London hotel in 1961, and his name is misspelled throughout [S3].
• The Army's Hawk missile is described as heat-seeking; it is radar-guided. 8th Air Force headquarters is placed at Fort Bliss, "more than 500 miles to the west, near El Paso" [S5].
• The book credits Corso and Trudeau with launching the CORONA satellite programme, whose first launch predates the posting Corso places himself in by two years [S1].

Corso's own service record independently contradicts the timeline the book asserts — see Philip J. Corso.
