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.

contributed to this instability were: (1) the turbulent motion of' the heated
air over the desert, (2) the change• in temperature ot air in the aneroid
val~e as intermittent clouds shut off' the sun, and (3) the overcompensation
caused by the valve-controlled ballast flow.
On this flight the .first "destruction device" was used for the purpose
of' brlbgi.ng down the balloon after a f'ixed time to prevent excessive inter-
ference in air-traffic lanes. This particular model was a clock-dri~en
device which failed to operate, probably because of' low temperatures causing
unequal contraction within the movement. Its action was to consist o.f de-
tonating an inflammable compound taped, to the balloon, rupturing iia side and
parmi tting a rapid escape of' the lifting gas.
