The Roswell Report: Fact versus Fiction in the New Mexico Desert was published in 1995 by Headquarters United States Air Force. It was written in response to Representative Steven H. Schiff's request and a General Accounting Office audit, and it contains Col. Richard L. Weaver's report and 1st Lt. James McAndrew's synopsis, along with attachments, appendices and photographs. The report says researchers found no evidence of an extraterrestrial craft or crew. It concludes that the 1947 debris came from 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-684, the SP.M-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.
