Project 10073 Record Card — Sheridan, Wyoming, April 20, 1961

This document consists of a Project 10073 record card and accompanying correspondence regarding a sighting in Sheridan, Wyoming, on April 20, 1961. The primary witness, an elderly woman described as a 'bird watcher,' reported observing a cigar-shaped, medium-gray object with no wings, fins, or appendages. The object was described as moving very slowly and evenly. The witness also reported hearing a strange sound, which she described as being 'off the carpet,' and which culminated in what the report characterizes as an 'imaginary sound.' The witness's daughter, who wrote the letter, attempted to correlate the sound heard by her mother with the sighting. The official conclusion recorded on the card attributes the incident to 'Emotional Strain.' The documentation includes a detailed narrative from the witness's daughter, who describes the mother's experience and the subsequent reactions of family members and acquaintances. The daughter notes that her mother was initially hesitant to report the incident for fear of being ridiculed, but eventually decided to share the information. The report indicates that the witness was in her home at the time of the sighting and that the weather was clear and sunny. The investigation did not find evidence of a physical object, and the final assessment dismisses the report based on the psychological state of the observer.
