Project 10073 Record Card — Jamestown, California, 6 April 1955

This document consists of a Project 10073 record card and associated teletype communications regarding a sighting on 6 April 1955 in Jamestown, California. The initial report describes a single, round, white object moving slowly to the west. The primary record card concludes that the object was definitely a weather balloon. However, the accompanying teletype communication provides additional, more complex details. It notes that at 1352 hours, witnesses reported seeing a balloon with something hanging down from it, which flight crews observed at 40,000 feet. The report also mentions a subsequent call received at 2155 hours from an individual at an Avenal hospital who claimed to have heard an explosion and seen an object that appeared to be a parachute. Two aircraft were sent to investigate and spotted a balloon in the area near Avenal. A separate UFOB Index Card (AISOP Form 5) for the same date and location identifies the object as 'Moby Dick', a term often associated with high-altitude research balloons of that era. The documentation reflects the standard military procedure for tracking and identifying aerial phenomena, ultimately categorizing the sighting as a balloon.
