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.

the nega,tive sign indicating a loss of lift.
From this equation we may approximate the amount of ballast re-
quired to compensate for the loss of superheat of the lifting .gas.
It is apparent, then, that the amount of superheat gained or lost
by a balloon 1 s ga• is of extreme importance to the control of the
,,_ight.
For this reason a transparent film has a definite advantage over a
reflecting fabric. For example, alumin~coated fabric balloons
floating at 40,000 feet have exhibited lifting gas superheat in
the neighborhood of 40°C.* Polyethylene balloons, on the other
hand, Show superheat of approximately lOOC under the same conditions.
Assuming a total weight of 30 kilograms in the balloon system, with
helium as the lifting gas ~ B ~ t ), the following compensation
at sunset, or when superheat is lost, will be necessary:
Aluminized fabric:

*This will explein the repid descent of flight with fabric balloons and
will show the need for high ·rates of ballast flow at sunset with poly-
ethylene balloon flig,hts (see Part III., "Summary of Flights," of this
report).
