The Roswell Report: Fact versus Fiction in the New Mexico Desert was published in 1995 by Headquarters United States Air Force. It was written in response to Representative Steven H. Schiff's request and a General Accounting Office audit, and it contains Col. Richard L. Weaver's report and 1st Lt. James McAndrew's synopsis, along with attachments, appendices and photographs. The report says researchers found no evidence of an extraterrestrial craft or crew. It concludes that the 1947 debris came from a Project MOGUL balloon train.

tion in the sunlight, turning from a milky white to a dark brown. He described
finding remains of balloon trains with reflectors and payloads that had landed in
the desert: the ruptured and shredded neoprene would "almost look like dark
gray or black flakes or ashes after exposure to the sun for only a few days. The
plasticizers and antioxidants in the neoprene would emit a peculiar acrid odor
and the balloon material and radar target material would be scattered after
returning to earth depending on the surface winds." Upon review of the local
newspaper photographs from General Ramey's press conference in 1947 and
descriptions in popular books by individuals who supposedly handled the debris
recovered on the ranch, Professor Moore opined that the material was most likely
the shredded remains of a multi-neoprene balloon train with multiple radar
reflectors. The material and a "black box," described by Cavitt, was, in Moore's
scientific opinion, most probably from Flight 4, a "service flight" that included a
cylindrical metal sonobuoy and portions of a weather instrument housed in a box,
which was unlike typical weather radiosondes which were made of cardboard.
Additionally, a copy of a professional journal maintained at the time by A.P.
Crary, provided to the Air Force by his widow, showed that Flight 4 was
launched on June 4, 1947, but was not recovered by the NYU group. It is very
probable that this Top Secret project balloon train (Flight 4), made up of unclassi-
fied components, came to rest some miles northwest of Roswell, NM, became
shredded in the surface winds, and was ultimately found by the rancher, Brazel,
ten days later. This possibility was supported by the observations of Lt Col Cavitt
(Atchs 17-18), the only living eyewitness to the actual debris field and the
material found. Lt Col Cavitt described a small area of debris which appeared, "to
resemble bamboo type square sticks one quarter to one half inch square, that were
very light, as well as some sort of metallic reflecting material that was also very
light .... I remember recognizing this material as being consistent with a weather
balloon."
Concerning the initial announcement, "RAAF Captures Flying Disc," research
failed to locate any documented evidence as to why that statement was made.
However, on July 10, 1947, following the Ramey press conference, the Alamogordo
News published an article with photographs demonstrating multiple balloons and
targets at the same location as the NYU group operated from at Alamogordo
Army Air Field. Professor Moore expressed surprise at seeing this since his was
the only balloon test group in the area. He stated, "It appears that there was some
type of umbrella cover story to protect our work with MOGUL." Although the Air
Force did not find documented evidence that Gen. Ramey was directed to
espouse a weather balloon in his press conference, he may have done so because
he was either aware of Project MOGUL and was trying to deflect interest from it,
or he readily perceived the material to be a weather balloon based on the
identification from his weather officer, Irving Newton. In either case, the materials
recovered by the AAF in July, 1947, were not readily recognizable as anything
special (only the purpose was special), and the recovered debris itself was
unclassified. Additionally, the press dropped its interest in the matter as quickly
as they had jumped on it. Hence, there would be no particular reason to further
document what quickly became a "non-event."
