Project Blue Book Case #1783. On August 2, 1952, a bright object was observed over Lake Charles, Louisiana — the third Blue Book unknown from this Gulf Coast city and its air base during the summer of 1952 (joining Cases #1870 from August 9 and #2045 from September 6). The concentration of three unknowns in a single city over five weeks was among the highest repeat rates in the entire Blue Book database.
Lake Charles AFB's jet pilot training mission meant the area's skies were consistently busy with high-performance aircraft. The August 2 sighting was the earliest of the three, occurring during the peak of the great wave when reports were arriving from across the country at unprecedented rates.
The triple occurrence at Lake Charles raised questions that applied to the broader phenomenon: were certain locations genuinely experiencing repeated anomalous activity, or were they simply producing more reports due to a combination of attentive observers and busy skies? Blue Book could not answer this question definitively.
No conventional explanation was found for any of the three Lake Charles cases. All were classified "Unknown."
