Project 10073 Record Card — Lincoln, Nebraska, 20 July 1955

This document consists of a series of records, including a Project 10073 Record Card and a formal teletype report, regarding an Unidentified Aerial Phenomena (UFOB) sighting that occurred on July 20, 1955, near Lincoln, Nebraska. The primary witness, a 43-year-old housewife, reported observing a single, round, silver object that appeared to be the size of a silver dollar when held at arm's length. The witness noted that the object was clearly spinning as it moved at a high rate of speed from the southwest to the northeast. The observation lasted approximately 15 seconds. The report was submitted by the 818th Air Division at Lincoln Air Force Base in compliance with Air Force Regulation 200-2. The official investigation, conducted by the Air Technical Intelligence Center (ATIC), concluded that the sighting was likely a misidentification. Specifically, investigators suggested that the witness observed the reflection of the sun off a highly polished aircraft. The report explicitly notes that the witness's non-technical background made it difficult for her to correctly identify the phenomenon, and that the reflection could account for the object's perceived size and appearance. The report also mentions that the witness was watching a formation of B-36 aircraft at the time of the sighting. Weather conditions at the time were reported as clear with no ceiling and 10 miles of visibility. A check with the Air Defense Command (ADC) weather office produced negative results regarding any unusual atmospheric phenomena. The documentation includes both the initial teletype report and subsequent index cards used for tracking the incident within the Air Force's UFO reporting system.
