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.

(2) Codeaonde
The modified radiosonde built by Brailsford and Co.,
Rye, New York,called the codesonde,has been found
valuable when knowledge of small variations in the
height of the balloon is not required. Using this
system, a radio transmitter is modulated by a Morse
code signal which is a function of pressure (and
temperature if desired). This system is useful for
tracking a balloon with aircraft since no recording
equipment is necessary tor data interperlation.
Each combination of dots or dashes may be identified
by ear, and with a calibration chart, the pressure
Which corresponds to the balloon's height may be
thus determined by anyone who can read Morse code
with a suitable radio receiver. T.he adva~tages of
using this system for a balloon which is to be followed
by aircraft include the fact that it is necessary to
receive only one complete code group tocompletely
identify the pressure level of the balloon. It is
thus possible to ~nterrupt the period of reception
without per.manently losing the altitude record. It
is expected that a balloon transmitter which can be
followed with an aircraft radio compass- will be used
in conjunction with this pressure modulator, giving
three-dimensional position data.
(3) Barograph
Many balloon flights pass out of the range of even
a network of receiving stations. When it is not
possible, because of weather or other considerations,
to follow the balloon with aircraft, a clock-driven
meteorograph may be added to the flight train to re-
cord data, such as pressure and temperature. It is
necessary to recover the balloon equipment to evaluate
this sort of record. With inland release points,
it has been possible to recover about 75~ of all
flights.
The model U-48 Lange barograph, shown in Figure 35,
is designed to give ~ record of atmospheric pressure
and the temperature of the barograph case. In order
to obtain a maximum spread of the pressure record
in the range at which the data is most useful, the
lin~ges are arranged so the.t recording begins at
about 500 millibars or around 19,000 feet, and may
be continued as high as the balloon rises. The
