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.

which switches four elements into the transmitter circuit in turn. Recently a motor making five revolutions per minute was used so that each temperature is transmitted for three seconds. The four elements are the free-air temperature, the gas temperature, battery- pack tempereture and a reference signal. This switch is supple- mented by a master program switch whicp alternately places the temperature switch and the pressure modulator into the transmitter circuit. The present arrangement is to permit the temperature data to be transmitted for about one minute in every fifteen. In this wt.y represente.tive temperature sampling may be obtained, without materially destroying the continuit,y of the pressure and ballast data. A second system or determining temperature makes use of the smoked drum of the barograph. By adding a temperature-activated pen, this unit makes a record of the temperature encountered. Since it is not the free-air temperature nor the temperature or the lifting gas but rather the temperature or the barograph itself, the data obtained has been or little value. Following the development of suitable temperature telemetering apparatus, this method was not used. c. Ballast Metering It is often very desirable to knowwl'ether or not ballast control equipment is operating properly during flight tests. For this purpose, two ~stems of ballast metering have been devised. It is possible (1) to record on an instrument which is balloon-borne or (2) to detect and telemeter information to the ground concerning ballast flow. Figure ~7 shows the automatic siphon which has been used in the AM-1 transmitter circuit for the telemetering of such information. A series of pulses of fixed frequency is transmitted whenever the contact arm of the automatic siphon is filled above a critical level. The electrolyte used is non-miscible with the ballast and rises and falls in proportion to the rise and fall of the aain arm of the siphon. This main arm empties when approxiDIIltely 3.5 grams ot ballast have been allowed to flow into it. As a consequence of this intermitte~t filling and emptying of the lines of the siphon, an intermittent slgnal of f'ixed.frequency is transmitted whenever ballast is flawing steadily. It is important that an electrolyte be used wHich will not freeze at low atmospheric temperatures and will not boil at the low pressures encountered. After a aeries of tests it was decided that a G4% solution of hydrochloric acid be used for altitudes up to 85,000 teet. It is necessary to use platinum wire for the contact points. In order to record in flight the functioning or the ballast control system a ballast recording mechanism has been developed in con- junction with the Lange Laboratories of Lexington, Kentucky.
