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.

Flight 68: Released from Alamogordo, New Mexico, 2033 :MST, May 10, 1948
Recovered at Val D•Or, Quebec ·
A .001 11 polyethylene balloon was the vehicle on this flight carrying a
barograph as ~11 as an early model of the Olland-cycle pressure modulator.
This flight was released at night with a fixed ballast flow of about 300
~rams per hour expected to keep the balloon afloat. From the barogram
(Figure 22) (12-hour rotation) it appears that the orifice did not permit
sufficient (if' any) flaw to maintain buoyancy during the first several
hours (perhaps the orifice was clogged or frozen). After a descent to about
:53,000 feet at 8\Jlri!'!ea floating level was maintained with 4 kilograms of
ballast available. The full flow rate could not have been maintained much
more than the 11 hours during which the balloon was at this pressure.

Figure 22
On this flight, oscillations in the pressure record were seen. With
no control system which could cause such behavior, they must be attributed
to atmospheric motion.
The descent point was compared with that expected from analyses of' the
pressure field. The results of a number or such analyses are shown in
