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.

Pressure Height: The height above mean sea level as determined fram pressure measurements used in this work with the N.A.C.A. Standard Atmosphere. Section 4. Flight Techniques The general techniques of preparing and launching controlled altitude balloons are patterned after those of the smaller radiosonde balloons. The treatment· of large • manned balloons has been studied. however • and inf'orme.tion of considerable value has been gleaned; as from the National Geographic Society . 11.12 reports of the flights of Explorer I and Explorer II , and from the book 15 13. 14 by Upson and Chandler • Fram these and other studies 'and from original experimentation with General Mills advice, a satisfactory technique of' handling controlled-altitude balloons has been developed. A. Infh.tion The lifting gas used for these lar~e balloons has been helium. The choice of gas was made on safety considerations. Hydrogen, however, has several advantages over helium. It will lift ~ more than helium and. due to its lower specific gravity, requires but 50% of the ballast release that helium requires to correct for disappearance of superheat at sunset. Helium, on the other hand, leaks and diffuses at a rate but 70% that of hydrogen. However • for long flights. hydrogen would prooably have more over-all economy of ballast. Inflation has been made through a low-pressure, diffusing manifold, feeding from a number of' helium tanks simultaneously to the balloon. The smaller balloons he.ve been inflated inside a .hangar, permitting very exact weigh-off of the balloon's free lift, thus predetermining the rate of' rise fairly well. The plastic balloons larger than 15 feet in diameter have generally been inflated out-of-doors, aa no hangar large enough for interior - 22 -
