Project 10073 Record Card — Yokota, Japan, 9 April 1961

This document is a Project 10073 Record Card detailing a sighting that occurred on April 9, 1961, near Yokota, Japan. The observation, which lasted approximately four to five seconds, involved a single object described as a flash of brilliant white light. As the object descended, it changed color to amber red. The report notes that the object appeared to be falling vertically and did not exhibit a tail until sparks formed a short trail at the time of its disappearance. The source of the report is identified as military. The official conclusion reached in the record card is that the object possessed all the characteristics of a meteor. The document includes supplementary pages that appear to be related correspondence or internal routing, though these pages are largely obscured or contain minimal legible text beyond the date and priority markings.
