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.

and a Sinclair paint solvent. The ballast valve or dribbler essentially
perform the same function as the Japanese altit·Jde control on the balloon
bomba yet it is simpler end permits use of a liquid ballast for better control.
Another ?ieee of ~~uipment that is under construction by Kollsman
Instrument Gomp&ny is a motor-s'"ritched rs.diosonde modulator. It presents
pressure data to the radiosonde transmitter as a variable resistance. The
meteorological data is programmed by" a samll Brailsford Electric motor. This
modulator will provide the contact that seals off the diaphragm in the
ballast valve. A compleie discussion of this equipment will be furnished
upon its delivery.
Sketches of balloon and rigging of the balloon to be used on to
the main problem are given in the appendix and are self-explanatory.
Computations
A chart showi~ the relation between altitude, gross lift, and
balloon size has been found necessary.
Data for it was computed usiDg mean aerological soundings as
reported in the Monthly Weather review for 1943.
A chemical term, molar volume (in cubic feet) l.'aS used as a term
relating the souzxling data with buoyancies of the balloons at various
altitudes.
Using the simple gas laws, the molar vol~ of dry air was
computed thus:
I. (1) Molar volume of any gas at standard conditions is 359 ft. 3
(2) From Monthly ~eather Review Jan. 1943, the mean sounding
data at 15 km for Lakehurst, N. J. is: Temperature -59.5°C
Pressure 120 mb.
