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 tem~·erature data obtained was or considerable value, especially
to determine the effect or insulation of the battery pack. It was
found on most flights where reasonable thermal insulation was applied
that the temperature of the pack remained above 0°C after several
hours of exposure at nighttime. The extreme observed was -lOOC.
Daytime flights had the added advantage or heating from the sun.
The temperature of the lifting gas at the ground was ordinarily
found to be somewhat below the temperature or the e.ir. This is due
to the extreme cooling encountered in the expansion or the compressed
gas as 1t was fed from the tanks into the balloon. During the rising
period, in daytime, the gas gained heat, since it cools adiabatically
lea& rapidly than does air {also less than the normal tropos~heric
lapse rate); at the floating level a differential of about 10 C
was common. A typical temperature trace is shown in Figure 35.

To permit the transmission of both temperature and pressure data by
one radio channel, a pe.ir or ,programming switches have been de-
signed and flight tested. The first is the temperature switch (Figure 36~
