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.
