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.

pending upon the speed or rotation of the mo- dulator motor. The pressure signal appears at any point along the record between or over- lapping the references depending upon the pressure. A sample record of this sort is shown in Figure 32. The Olland cycle acts as a ~itching unit for the test oscillator (see Figure 33) whose agnal· is fed into the Brush amplifier and finally to the recorder. By adjusting the resistors in the test circuit, the frequency ot oscillation may be adjusted. Since within the usual range, the frequency of oscillation is approximately additive when the two signals over- lap. the suggested frequencies are about 4 cycles per second for pressure and 8 cycles per second for refer· ence. When overlapping signals are being recorded the frequency will be about 12 cycles per second which is easily recognizable on the record. The calibration of the modulator unit should be in steps of 25 to 30 millibars in order to have at least three points within each turn of the helix. Evaluation of the record is accomplished with the aid of a nomogram divided into 100 equal parts. The record is laid on the nomogram with the leading edge of the first reference on the zero line and the leading edge of the second reference on the lOOth line. The position of the leading edge of the pressure signal is then read to the nearest third of a division on the nomogram. If one complete turn of the spiral represents 75 millibars, it is thus possible to read the pressure to an accuracy of one- three-hundreth of 75 or about one-quarter milli- bar. In evaluating the record the tape should be kept parallel to the horizontal lines on the nomogram or perpendicular to the zero line in order to avoid errors in ir..terpretation. The total motion of the pen arm of the modulator is normally 12 to 14 turns of the spiral. Therefore, there will be the same number of points at which the pressure and reference signals overlap. The calibration curve (Figure 34) is drawn to show pressure from zero to surface pressure (about -57-
