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.

In general. a balloon should be manufactured so that any failure
should occur first in the fabric or film and thus the tensile
stress of this fabric or film will be the factor in determining bursting
pressure.
Since the non-extensible balloons used in constant-level work by
the N.Y.U. group have been of the open-appendix type. bursting
due to excessive super-pressure has not been a problem. Strength
of the balloon must be considered. however. from the standpoints
of back pressure induced during rise of a full balloon and pressure
distribution of the lifting gas itself in.side of the balloon.

It was shown in the previous section that the pressure diff-
erence across any portion of the balloon surface may be equated:
