Project 10073 Record: Sighting Report - McHenry, North Dakota, April 1966

This document contains a collection of records related to a UFO sighting reported in April 1966 near McHenry, North Dakota. The primary witness, a local farmer, reported observing an object near a Minuteman II missile site (I-37). The witness described the object as resembling glass bulbs arranged in a ring, approximately eight feet across, and emitting a sound similar to a tractor backfiring. The witness initially did not report the incident but later contacted authorities due to concerns about the object's proximity to the missile silo. The report includes a completed U.S. Air Force Technical Information questionnaire, where the witness provided details about the object's appearance, behavior, and flight characteristics, including an estimated speed of 80 m.p.h. and an altitude of 1,500 feet. The witness also provided hand-drawn sketches of the object. The official Air Force conclusion, documented by Major Hector Quintanilla, Jr., was that the report was 'Information Only.' The investigators noted that because the report was filed significantly after the actual sighting, the data was likely distorted and impossible to verify. The document also contains correspondence regarding a separate 1959 C-118 aircraft crash near Tacoma, Washington, which the Air Force maintained was caused by pilot error and not related to any UFO activity, despite inquiries from the public and researchers.
