PROJECT 10073 RECORD CARD — Platte County, Missouri, August 1955

This document is a Project 10073 Record Card documenting a civilian sighting in Platte County, Missouri, occurring in August 1955. The witness reported observing a single object for over two hours, beginning one hour after dark. The object was described as moving in a manner similar to a rotary-wing aircraft, moving up and down, forward and backward, and remaining stationary at times before executing a 'tremendous burst of speed.' The witness noted a fluorescent blue color, lights on the edge that appeared to be windows emitting a bluish then reddish glow, and a high-pitched hum that was felt more than heard. The witness also noted that they were sensitive to high-pitched sounds and that the humming irritated their nerves. The report was not submitted until 1958, three years after the event. The evaluating agency, ATIC, dismissed the report as an 'unreliable report' due to the significant delay in reporting and the lack of positional data or details regarding the object's disappearance. The official conclusion suggested that the sighting was likely the result of an 'overactive imagination' and noted that Venus, Jupiter, and Mars were below the horizon during that time, effectively ruling out astronomical phenomena as a simple explanation for the light. The case was ultimately closed without further investigation.
