UFO seen in Gransmere in 1957

Summary

A civilian observer in Gransmere, New Jersey, spotted a white object the size of a dime with a white vapor trail on November 6, 1957. The object was seen for 30 minutes and was moving toward the southeast. Although no photos were taken, the report suggests it could be a balloon, given the wind direction. Investigators concluded the object was "possibly" a balloon, but other explanations were not ruled out. This case is part of the records from Project 10073, an initiative from that era to document unidentified aerial phenomena.
