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.

is not useful when the changes occur at a nearly constant altitude due to the width of the steps and the ambiguity of direction of vertical motion. Two pressure measuring systems have been found satisfactory for use in constant-level work and are discussed below. For a discussion of the radio transmitters which have been used (the standard T-69 and the NYU AM-1), see Technical Report No. 2, Balloon Project, New York University Research Division. ## (1) Olland Cycle Pressure Measuring Instrument This instrument, shown in Figure 31, is used in balloon flights as the primary pressure measuring unit, as it will continuously measure pressure without ambiguity. It modulates the transmitted radio signal at intervals whose timing is determined by the pressure of the air at the balloon's position. As presently designed, the modulator contains a standard Signal Corps ML-310E radiosonde aneroid unit, a rotating cyclinder of insulating material with a metal helix wound around the cylinder, and a 6-volt electric motor which rotates the cylinder. There are two contacting pens which ride on the cylinder and conduct electrical current when they touch the helix. One pen is fixed in position and makes a contact at the same time in each revolution of the helix. This contact is used as a reference point for measuring the speed of rotation of the cylinder. The time that the second one, which is linked directly to the aneroid cell, makes contact with the spiral, is dependent on the cylinder speed and on the pen position which is determined by the pressure. By an evaluation chart, the atmospheric pressure can be determined as a function of the relative position of the pressure contact as compared to the reference thus eliminating all rotation effects but short term motor speed fluctuations. Preparation of the modulator for flight consists of the following steps: (a) Test the motor operation. When a 6-volt battery is inserted in the motor circuit with the proper polarity, the motor should run smoothly at one revolution per 60 to 80 seconds. Noisy operation is probably a sign of dirty or corroded
