AI-Generated Summary
A 1951 Project 10073 record card detailing a pilot's sighting of a round, 40-50 foot object over Big Bear Lake, California. The investigation concluded there was insufficient data to identify the object, noting a possible balloon origin.
This document is a Project 10073 Record Card documenting an unidentified aerial phenomenon observed on January 14, 1951, near Big Bear Lake, California. The observation was reported by a pilot at 2038Z. The object was described as round, measuring 40 to 50 feet in diameter, and was observed at an altitude of 30,000 feet. The object exhibited no sound, no exhaust trail, and no maneuverability, and was traveling on a westerly course. The record indicates that no photographs were taken and there was no radar contact. The official conclusion reached by the evaluating agency, ATIC, was that there was insufficient data for a proper evaluation. The comments section notes that while the general description suggests a possible balloon sighting, the report is fundamentally incomplete. Specifically, the duration of the sighting was not recorded, and the provided wind data was ambiguous, failing to specify whether it represented a current condition or a forecast, and lacking necessary altitude or location context.

Insufficient data for evaluation
The report indicates a possible balloon sighting, but the lack of duration, exact wind data, and ambiguity regarding whether the wind report was a condition or a forecast prevents a definitive evaluation.
