Just before New Year Eve we found and disposed SD250 which was placed as the demo charge. The bomb was found in western Bosnia and Herzegovina, town Bihać at the location of the WWII German airport. The bomb was found in the vertically placed concrete pipe covered with the concrete plate. No baseplate was on bombs body tail end and wiring was found along but no detonator or sympathetic charge. 9 years ago we had same case with SC250 less than 100 meters away. It is supposed that these bombs were used as demolition charges to render the airstrip useless in the case of an emergency.

There are testimonies about some 16-18 pcs. But area is built up now, so over airstrip streets and houses arose. We have no record about bombs disposed before 1995. in the area but we have some leads we plan to inspect.
