Mark in photo during Chambley-Bussières balloon festival resolved as a novelty balloon

Summary

On August 5, 2007, during a hot-air balloon festival at the former Chambley-Bussières air base, a participant found a suspicious mark in one of his photographs that matched neither a balloon, a bird, nor a camera artifact. The case reached GEIPAN after media coverage, with no direct visual observations of the object.

Local investigator Christian Comtesse gathered additional images showing the same mark. One detail-rich photo was analyzed by François Louange, who estimated the object was 75 cm to one meter in size and about 300 meters from the photographer. In March 2008, a balloon pilot confirmed having seen a child's fish-shaped balloon, which closed the case. GEIPAN classified it as A, highlighting the value of collaboration between local investigators and photographic analysis techniques.
