Project 10073 Record Card - Duluth, Minnesota - 7 August 1952

This document is an Air Intelligence Information Report regarding a UAP sighting on August 7, 1952, at the Williamson-Johnson Airport in Duluth, Minnesota. The witness, a CAA meteorologist with 24 years of experience in pilot balloon observations, reported seeing a small, bright object while performing a routine weather balloon tracking procedure. The object, described as having the color of sunlight, was observed through a theodolite for approximately two minutes. The witness noted that the object appeared to be motionless for one minute, after which he could not definitively determine if it remained stationary, climbed, or descended due to the limitations of the observation. The witness explicitly stated that the object's movement across the field of vision was not caused by any defect in the theodolite instrument. The report includes a detailed observer questionnaire where the witness confirms he was outdoors, using a theodolite, and that no other individuals were present to corroborate the sighting. The witness emphasized that he had no opinion on the composition or cause of the object, noting only that he could see light. The report concludes that there was no physical evidence, no interception, and no identification of the object. The reporting officer, 2d Lt. Loren F. England, noted that the witness should be considered reasonably reliable. The document includes the original record card, the intelligence report form, and the completed observer questionnaire, providing a comprehensive account of the incident as reported by the witness.
