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 75: Released from Alamogordo, New ~~xico, 1010 MST, July 20, 1948
Recovered at Hollister, California
In order to reach higher altitudes than was possible when 20-foot plastic
balloons were used, a 70-foot, .001" polyethylene cell was flown an Flight
75. To determine the duration of buoyancy of this type of balloon no con-
trols were used. Despite this, the balloon remained aloft for more than 60
hours and successfully withstood the loss of superheat occasioned by at
least two sunsets. From the height-t~e curve of this flight (Figure 29)
the very marked effect of superheat is apparent.

The record of the barograph was not complete since the clock stopped each
night (clearly recording the lowest elevation reached, however) and ran
down completely after 56 hours.
Since the small external appendix with cardboard stiffeners was not
suitable for the large balloon, a new design with aluminum formed stiffeners
(Figure ~0) was used. This type of appendix closer worked well on later
flights, and it is likely that the long duration of this flight may be attri-
buted in part·to satisfactory closing off of the aperture. In addition to
