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 actual atmospheric distribution. however. does not indicate an
adiabatic lapse rate for air but rather a lapse rate which varies
with altitude. For. the troposphere the lapse rate of the atmosphere
averages -1.980C/1000 .ft. It may be shcrrm then that in the tropo-
sphere a rising balloon will get warm with respect to the air
(neglecting ventilation and radiation effects} at a rate of
1.98 - .57 : 1.4lOC/lOOO ft. In the tropopause the lapse rate of
the atmosphere is zero. Thus the lifting gas (if helium} will
oool relative to the air at a rate of .570C/1000 ft.
Similarly, in the stratosphere, the lifting gas will cool relative
to the air at a rate of 2.24 ~ .57 : 2.81°0/1000 ft. This effect
is plotted as Figure 22.

Figure 22. Lapse rate of air and helium.
Here. below point A, the lifting gas will be warmer than the air.
Above point A, the lifting gas will be cooler than 'the e.ir. The
effect of this temperature difference on the lift (as shovom in the
previous section} is approximately lll = L ..ai I
T (I- 8)
Thus. as a balloon system passes through point A. it will have less
lift then at release. This effect has been observed on several
flights. where a balloon system slowed down during ascent through
a ~mperature inversion.
Since the effect of the sun in heating the lifting gas decreases
the effect of different lapse rates, the effect is not as noticeable
during the day as at night. At night the balloon system may pass
through an inversion, lose its lift, and remain at an altitude much
below its estimated floating altitude until warmed by the sun's rays
at sunrise.
