here we have an area concerning an air raid on the night of february 15th 1904 it was a major raid targeting berlin. with over $800.00 aircraft and including a diversionary attack. an airborne mine laying operation with 44 bombers over the bay of kiel if you see. in total these aircraft dropped over $270.00 mines. we have detailed documentation of the raid including the british plans so we know these aircraft actually took off and conducted the diversionary attack and the mines were transported into this area. to locate mines dropped from the skies because it has to consult mountains of british american and jim in files he and his team are generally only allowed access for a few days at a time. when the shows are busy a typical research visit to an archive with a team of 3 or 4 people might produce 121-2000 pages of material for analysis if
