UFO seen in Grand Rapids Michigan in 1961

Summary

In October 1961, an officer at the Grand Rapids Air Force Station in Michigan observed between 2 and 3 bright lights slowly moving east. Witnesses noted that the lights blinked or rotated, and remained visible for 20 minutes. Although no photos were taken, the report notes that the movement and direction of the lights matched the wind conditions, suggesting it could have been a balloon. However, no information was obtained about the launch location or time, leaving some mystery around the case.

The Air Force concluded it was likely a balloon, but did not rule out the possibility of an unidentified object. This document, classified under Project 10073, shows how UFO reports were evaluated based on available data, often leaving questions unanswered.
