Insufficient Data

Summary

On July 29, 1949, a military pilot reported seeing smoke over the Chaplina area of northeastern Siberia. The pilot was flying at about 2,000 feet at a position over the Pacific listed as 64 degrees 10 minutes north, 172 degrees west. The report came from an Alaskan Air Command intelligence report. The Air Force conclusion was "other (anti-aircraft firing)." The report became part of Project 10073, the Air Force's official record for unidentified flying object reports.

The pilot reported four heavy black puffs of smoke over the area. The puffs formed slowly and dissipated rapidly at regular intervals of about one to two minutes. Each burst formed after the one before it had faded away.

The weather at the time was full cloud coverage with tops at 1,200 feet, unlimited visibility, and blue sky. The preparing officer noted that the behavior was not exactly like known anti-aircraft bursts, but stated that the phenomenon could possibly be anti-aircraft firing.
