Marks on photographs of a regatta in Crozon

Summary

In April 2007, a witness in Crozon photographed a regatta in the Brest roadstead and later discovered unexplained marks in the images. No visual observation had been made at the time of the shot, and no similar reports were filed for the area that day. The photographs alone do not provide sufficient information for rigorous analysis. Given the usual presence of birds in the roadstead, the most likely explanation is that birds in flight were inadvertently captured. Classification C.
