Project 10073 Record Card — Boulder City, Nevada, 15 April 1954

This document is a Project 10073 record card and associated military message regarding an Unidentified Aerial Phenomena (UAP) sighting that occurred on 15 April 1954 in Boulder City, Nevada. The primary witness, described as a reliable civilian, reported observing a single, elongated object at approximately 0600Z. The object was estimated to be 150 feet in length and featured reddish lights emanating from portholes along its sides. The witness noted that the object produced a prominent buzzing sound of medium pitch, but lacked any tail, trail, or exhaust. The object maintained a steady, straight-line flight path before disappearing. A second observer, identified as an explorer on the staff of Brigham Young University (BYU), reportedly viewed the object through 6x30 binoculars, though this individual could not be contacted for further follow-up due to an unknown location. The weather conditions at the time were reported as clear with a full moon, with no cloud cover or thunderstorms. The report was processed by Captain Curvin E. Miller Jr. of the United States Air Force, who noted that there was no information presented that conflicted with an aircraft analysis. The document serves as a formal record of the incident in compliance with Air Force Regulation 200-2.
