Insufficient Data

Summary

On January 14, 1951, a pilot reported a round object near Big Bear Lake, California. The report is part of Project 10073, the Air Force's official record for unidentified flying object reports.

The witness described the object as round, about 40 to 50 feet in diameter, at an altitude of about 30,000 feet, moving on a westward course. No speed was given. There was no sound and no exhaust trail. A wind forecast was noted from 360 degrees.

The Air Force listed its conclusion as insufficient data for evaluation. Investigators noted the general description suggested a possible balloon, but the duration was not reported and exact wind data was lacking.
