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.

## F. Radar and Optical Tracking Because of their limited range, ground radar sets and theodolites were only of minor value in tracking balloons. Sets such as the SCR-584, the SPM-1, and MPS-6 are suggested when the balloon is expected to remain within the 60 to 80 mile range. ## VI. INSTRUMENTATION ## A. Altitude Determination To provide accurate, sensitive and readable records of the pressure (altitude) encountered by the balloon, various systems have been tried. A modified radiosonde-type aneroid pressure capsule (Signal Corps ML 310-/) has been the basic sensing element, but three different systems of modulation of the radio signal as a function of pressure have been used. ## (1) Standard Diamond-Hinman Radiosonde Pressure Modulator Seen in Figure 29, the standard Diamond-Hinman radiosonde system provided first pressure sensor used. As the pen arm is pushed Figure 29. Schematic diagram, Diamond-Hinman radiosonde system. across the commutator by the aneroid capsule, it falls on alternating insulators and conductors attached to three circuits.
