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.

temperature-compensate the diaphragm, the other to
insulate and shield the valve from radiation.
Using the ceiling-control system, flights of less than
24 hours not passing through sunset, may be held at
ceiling by use of a nonextensible balloon and a simple
fixed rate of leak to over-compensate diiTusion losses.
The constancy of level will be better the lower the
diffusion and the lower, therefore, the rate of rise of
the ceiling. The automatic control is needed for flights
lasting through a period in which day changes to night.
8. Preliminary trajectory analysis of two constant-
level balloon flights, 7 July 19477
The most striking feature of the constant-level bal-
loon flight (Flight 11, fig. 9) originating at Alamogordo
Army _-\ir Base at 05hQ8m MST 8 on 7 July 1947 is the
disagreement between the actual trajectory and the
trajectory that might have been estimated from routine
upper-wind reports. In this connection the observations
from the \Veather Bureau stations at El Paso, RosweH,
and .-\lbuquerque have been examined, since the path
of the balloon was contained within the triangle formed

by these stations. Over El Paso, the wind direction
at 16,000 ft (the approximate average altitude of the
balloon during the greater part of the flight) was
approximately SW at 03h, ESE at 09\ and ESE at
15h. Over Roswell, the apparent average wind direction
at 16,000 ft was S during this period. Over Albuquerque,
which was considerably farther from the path of the
balloon than the other two stations, the wind direction
at 16,000 ft was variable between WSW and SSE during
the interval from OJh to 15h. In contrast with these
observations is the fact that the constant-level balloon
floated in an essentially steady \VSW current between
06h and 09h.
In fig. 8 the wind observations at 16,000 ft have been
plotted for El Paso, Roswell, and Albuquerque for 03h,
09h, and 15h. The wind directions at 14,000 ft, 16,000
ft, and 18,000 ft (only the intermediate level is shown
in the figure) are all contained in the 150-degree sector
between directions 90° and 240°; yet the mean motion
of the balloon (approximately 265°) between 05h48m
and 13hll m falls entirely outside this sector.
An indication that this local WSW current was of
small depth is given by a special upper-wind observa-
tion made at White Sands at about 13h. The observa-
tion in question recorded a wind direction of 250° at
16,000 ft, which is in excellent agreement with the first
