AI-Generated Summary
A civilian reported a white object in the sky over Denver on 13 May 1964. The military investigated the sighting as a potential satellite, but closed the case due to insufficient data after the witness failed to return follow-up forms.
This document details a UFO sighting reported on 13 May 1964 in Denver, Colorado. A 24-year-old medical technician observed a white, pin-head-sized object in the sky for approximately 15 to 20 minutes. The object was described as moving in a straight line toward the northeast before disappearing over the horizon. The witness, located on the roof of Mercy Hospital at 17th and Milwaukee Street, reported the sighting at 0425Z. The military investigation, conducted by Lowry AFB and the Foreign Technology Division (FTD), attempted to gather more information by sending FTD Form 164 to the witness, but the forms were never returned. The official analysis suggested that the object's description and motion were consistent with a satellite observation, specifically noting that the ECHO I satellite passed over Colorado at 10:38 PM, though this was approximately 40 minutes after the reported sighting time. Due to the lack of follow-up information from the witness, the case was officially classified as having insufficient data for evaluation.
Since forms were not returned the case is carried Insufficient Data.
