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.

jFabr1c
The physical and chemical properties needed in a balloon material
are: (l) chemical stability, (2) low permeability, (3) high tensile
atrengtb, (4) low brittle temperature, (5) high tear resistance,
(6) high transparency to heat radiation and (7) light weight.
In Table 1 the properies of 7 plastics and 2 coated materials are
given. From this data polyethylene and saran appear to be the most
sui table films.

Having decided upon the proper fabric to be used, an effort was
made to interest a number or companies in the fabrication and
production of balloons. The first supplier or balloon• ..d. or
·polyethylene was Harold A. Smith, Inc., lfame.roneck, lrew York.
In these balloons, 4 and 8 mil sheets were heat sealed to to~
a spherical cell open at the bottom. Load attachment tabs were
set into the fabric and loading lines ran from these taba to a
load ring. This method of' supporting the load proved to be un-
sa ti sfac tory.
