Documents / FOIA release
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.

Also used during Project MOGUL were balloons developed by Seyfang Laboratories, the inventors of the first Macy's Thanksgiving Day Parade balloons. These balloons were easily mistaken for flying saucers due to their shape and metallic exterior coating.
