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.

The following statistics for a given pressure (1001.8 ~il!ibars) were computed: on the mean within 0.1% or mean " o.2% " II " 0.3% " " " 0.4% " " " 0.5% " " N .Y .'J. Shop Model L-416 12.5% 25 % 41.5% 62.5% 75 % 95.6% Bra:Dsford Model B-501 34 % 50 % 70.5% 85.5% 91 % 100 % Other conclusions arrived at as a result of this test were: (a) Since changes of speed of the motors did not occur simul- taneously in the two instruments, the speed changes probably are not due to slight changes in pressure or temperature. (b) Sensitivity varied from 0.1 to 0.9 millibars. (c) Sensitivity increased with increase of rate of pressure change. It was recommended as a result of these tests that the records of flights when the balloon is floating be read to the nearest two-tenths of a percent of a oycle,or approximately two-tenths of a millibar, for high accuracy. ~ben using the instruments manufactured by Brailsford and Co., satisfactory accuracy will be attained, if necessary, when the record is read to the nearest one-tenth of a percent of a cycle. In the second group of tests the pressure was reduced slowly to about 20 millibars and increased to sea-level pressure at different temperatures. The most comprehensive series of calibrations wes made with the first instrument made by Brailsford and Co. Two runs were made at room temperature ( 22_10 C), one at -lOOC, one at -30 to 37°C and one at -56 to -620C. On the last test at the lowest tempera- ture, the unit was found to be completely unreliable. The cause of failure was the erratic· motor operation at extremely low temperatures. This had been observed previously during flights when the Olland-cycle was not thermally insulated. The other curves were plotted on a single chart in order to study their spread (see Figure 31). The envelope of curves thus obtained showed no regular temperature effect over the range +2,°C to -370C. In general, the envelope was less than 10 millibars wide although at some higher pressures it was as much as 12 millibars wide. The curves at low pressures fell closest together and were all within 3 to 4 millibars apart between 50 and 150 millibars and 6 millibars apart between 150 to 200 millibars. -70-
