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.

gears or poor alignment of the rotating cylinder. The motor gears may be cleaned with carbon tetrachloride and a small clean brush. If the trouble is due to misalignment, the instrument should not be used since this will affect the rotation at a non-uniform rate and thus destroy the entire accuracy of the record. (b) Calibrate the instrument. The following equipment is required for the calibration: Vacuum pump Bell jar Base plate with at lest 4 electrical leads Manometer Tape recorder The vacuum pump should be capable of evacuating the bell jar to a pressure lower than that to be reached by the balloon in flight. A pressure of ten millibars, corresponding to about 100,000 feet elevation is usually a good minimum. Four wires are necessary to conduct the six volts to the motor and to transmit the reference and pressure signals. The wires must pass out of the bell jar through an air-tight seal in the base plate. The base plate also needs a tube leading to the manometer and a tube to the vacuum pump. It is advisable to use two separate tubes rather than placing the manometer lead in the same line as the pump lead in order to obtain the pressure in the bell jar rather than that in the pumping line. In operation the negative line of the battery leads is used as the ground connection of the output signal. A tape recorder such as the Brush Development Co. model BL-902 oscillograph and amplifier BL-905, is needed to record the signal both during calibration and during the balloon flight. The Brush recorder is used at present and the discussion of the operation will be made in terms of the characteristics of this instrument. When using the slow speed of the recorder, which feeds the paper at the rate of 30 centimeters per minute, the distance between successive reference marks will be 30 to 40 centimeters de-
