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 58: Released from Alamogordo, New Mexico, 2033 MST, May 10, 1948 Recovered at Val D'Or, Quebec A .001" polyethylene balloon was the vehicle on this flight carrying a barograph as well as an early model of the Olland-cycle pressure modulator. This flight was released at night with a fixed ballast flow of about 300 grams per hour expected to keep the balloon afloat. From the barogram (Figure 22) (12-hour rotation) it appears that the orifice did not permit sufficient (if any) flow to maintain buoyancy during the first several hours (perhaps the orifice was clogged or frozen). After a descent to about 33,000 feet at sunrise a floating level was maintained with 4 kilograms of ballast available. The full flow rate could not have been maintained much more than the 11 hours during which the balloon was at this pressure. Barograph Record Of G.M. 20 ft. Plastic Balloon With 300 gm/hr Fixed Ballast Leak RELEASED AT ALAMOGORDO, N.M. - 2033 MST, 10 MAY, 1948 RECOVERED AT VAL D'OR, QUEBEC, CANADA-24 MAY,1948 ESTIMATED DURATION-24 1/2 hrs. ## Figure 22 On this flight, oscillations in the pressure record were seen. With no control system which could cause such behavior, they must be attributed to atmospheric motion. The descent point was compared with that expected from analyses of the pressure field. The results of a number of such analyses are shown in
