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.

Corps ML-310/ radiosonde aneroid unit, a metal helix on a rotating cylinder of insulating material, and a 6•volt electric motor which rotates the cylinder. There are two contacting pens which ride on the cylinder and c~lete the modulator circuit of the transmitter when they touch the helix. One pen is fixed in position and makes a con- tact at the same time in each revolution of the helix. This contact is used as a reference point tor meaauring the speed ot rotation of the cylinder. 7he time that the second pen (which is linked directly to the aneroid cell) makes contact with the spiral., is dependent on the cylinder speed and on the pen position which is determined by the pre.ssure. By an evaluation chart, the atmospheric pressure can be detennined as a function ot the relative position of the pressure contact as compared to the reference, thus elimina~ing all rotation effects except short- term motor speed fluctuations. The operation of this unit is described in detail in Section li, "Operations," ot this report, pages 64-63. Some of the units flown have been made in the shops of.the project, while others have been coJII!lercially supplied. The following specifications have been set up for perfor.me.nc& of the Olland-cycle: Pressure range: 1050 to 5mb. Temperature range: +300C to -300C Accuracy: t0.2 mb. Readability: to.l mb. A number of tests have been made on the accuracy of the Olland- Cycle module. tor. The tests were of two types. '!be first was made running the unit at room temperature while the pressure remained constant. In the second, the pressure was varied tram surface pressure to about 20 millibars several times at diff- erent temperatures. In testa of the first type, the maximum variation of pressure for a given contact pen poli tion was 1.3 millibars in a series of 182 revolutions. The most comprehensive tests of this~ were made with two Olland-cycles in the same bell jar rmning for three hours and ten minutes. Due to differences in speed of revolution, differ- ent numbers of revolutions were recorded in the time interval, 138 being made by instr.ument No. L-416 and 181 by instrUIII8nt No. B-501. No. L-416 was made in the shops of the Research Divi- sion and uaed a Brailsford 6•volt (1 rpm nominal speed) motor, hard-rUbber cylinder with 8 turns per inch of .010" nickel wire on a t" aluminum plate base. No. B-601 was ade by Brailsford and Co. to Balloon Project specifications. I~ had the aame 6-volt motor, a paper base bakelite cylinder with 8 turns per inch of .01011 nickel wire and was mounted on a 1/16" sheet aluminum frame. -69-
