The Roswell Report: Fact versus Fiction in the New Mexico Desert was published by Headquarters United States Air Force in 1995. The Black Vault distributes this copy. It reproduces the report by Col. Richard L. Weaver and the synopsis by 1st Lt. James McAndrew, both written after a General Accounting Office inquiry requested by Representative Steven Schiff. The Air Force search found no evidence of an extraterrestrial craft or crew. It concluded that the Roswell debris most likely came from NYU Flight No. 4, a Project MOGUL balloon train.

## Flight 63: Released from Alamogordo, New Mexico, 1116 MST, May 13, 1948 Descended at Alamogordo, New Mexico
On this flight a Seyfang Laboratories balloon, made of neoprene-coated nylon, was flown with a valve in the appendix set to open after an internal pressure of 0.02 psi was built up. On an earlier flight (59) such a balloon was flown with no valve but an appendix held closed with a rubber band; it ruptured upon becoming full.
Both a constant ballast-flow orifice and an automatic ballast control were used to keep this balloon buoyant. In addition to the ballast, a surplus of buoyancy might have been acquired when super pressure was built up inside the cell. Despite these controls, the balloon began to descend after a short period of floating, and its descent was not checked (Figure 24).

An analysis of the acceleration which could be gained from a loss of superheat indicated that if the coated fabric had absorbed radiation and gained $ 5 0^{\circ} \mathrm{C} $ over the outside air, the superheat thus obtained would be so great that its subsequent rapid loss (as by ventilation) could not be compensated for even with the ballast flowing at full rate. To improve the analysis of balloon flights, a measure of the temperature difference between lifting gas and air temperature was suggested. Report, cited by the archive.
