PROJECT 10073 RECORD CARD — 21 Sep 55

This document consists of a Project 10073 record card and associated teletype communications regarding an aerial sighting reported on September 21, 1955. The sighting occurred at 2300Z at coordinates 36.3N 73.55W in the Atlantic Ocean. The witness, identified as the SS Alcoa Pegasus, reported observing a 'suspicious and strange glowing' object for approximately 10 minutes. The object was described as being at an altitude of 23 degrees, moving slowly upward with a circular motion. The witness noted the object was a 'possibly very large illuminated balloon' that was clearly visible before slowly disappearing. Subsequent military communications, including a report from Commander Jeadf Stewart, linked the sighting to Operation 'Moby-Dick High'. An official follow-up message from the Eastern Sea Frontier confirmed that the sighting was likely a balloon connected to this operation, specifically identifying it as track number /-12-W, which was confirmed to be in the area of the sighting at the time of the report. The Project 10073 record card formally concludes the incident as a 'Moby Dick Balloon'.
