Analysis of Radar and Air-Visual UFO Observations
on 24 October 1968 at Minot AFB,
North Dakota, USA

The manuscript was prepared from June to August 2005, and translated in November 2005, with additional editorial work by Thomas Tulien and Prof. Suzanne Jones. The two discussion sections were added in March 2006. I would like to thank my colleagues Thomas Tulien, James Klotz (USA), and Martin Shough (Scotland), who have accomplished a colossal job of historical recreation and collection of data. Without their tenacity and concern in checking the smallest details we would know very little about this extraordinary observation. Finally, and most certainly, thanks to all direct protagonists of these events who agreed to speak and clarify their personal observations after more than thirty years. The USAF did not classify this observation, however, considering their responsibilities, these witnesses were naturally obliged to remain silent, or jeopardize their professional careers. The end of the Cold War, and the fact that most are now retired has certainly contributed to the release of the information. Without their contributions we would not have been able to successfully complete this analysis.

Editor’s note: The presentation of this study has been organized into five parts that include two discussion sections and three appendices. Part 1: Basic Information Concerning Minot AFB and the UFO Events. Part 2: Description of the B-52 Radarscope Photographs. Part 3 is a 2-Dimensional Analysis of the Photos. Part 4 is a 3-Dimensional Analysis of the Photos, with a discussion of the B-52 Altitude and Tilt-up Angle of the Radar Antenna. Part 5 considers the possibility of an Ionized Cloud Surrounding the UFO and the physical effects, including a discussion of the Photometric Study of the UFO. The appendices consist of App. 1: a reconstruction of the B-52 Timeline and discussion of time discrepancies; App. 2: Descriptive Measurements of the Photos; and App. 3: is a collection of Observer Accounts of the UFO Events from the documents.
