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.

mainte.n&nce ot the purity of the lifting gas. this balloon floated in a
region of very low preasure. thus reducing the loss of buoyancy by diffu-
sion.

A third factor contributing to the long flight was the heat gained by
adiabatic compression of the helium during descent. In the temperature in-
version of the stratosphere this adiabatic heating would add to the buoyancy
by superheating the lifting gas.
From this flight it becomes apparent that the control required to maintain
buoyancy at high levels is much smaller than that at low levels. On the next
day. before Flight 75 had ended. a second 70-foot balloon was flown with
standard automatic ballast controls. and this flight 11as never recovered. Pre-
sumably the marked easterly flow then observed above 60.000 feet carried this
second flight into the Pacific Ocean.
Radar~ RDF and theodolite were used to track the balloon.
