Project 10073 Record Card — Lincoln Park, Michigan, 23 April 1962

This document contains a Project 10073 record card and associated correspondence regarding a UFO sighting in Lincoln Park, Michigan, on April 23, 1962. The witness reported observing a very bright object in the western sky for approximately one hour and fifteen minutes. The witness described the object as appearing like a light, which moved slowly toward the horizon before flashing and disappearing. The witness provided additional details in a questionnaire, noting that the object was brighter than the stars and that they had observed similar phenomena in the past. The witness also submitted photographic film for analysis. The Foreign Technology Division (FTD) requested an analysis of the prints and negatives. The Photo Exploitation Division subsequently examined the color transparencies and concluded that nothing resembling the witness's description could be discerned. They noted that the images only showed normal advertising display lighting and that no stars or starlike objects were detectable. The official conclusion recorded on the project card states that the planet Venus was the probable cause of the sighting, as it was setting at the reported location at 21:30 with a magnitude of -3.3. The observed flashing was attributed to atmospheric refraction and inconsistencies in the air mass. The file includes the original record card, the witness's completed questionnaire, correspondence between the FTD and the witness, and the results of the photo analysis.
