Hello pssubers
The problem with the old munition is very big. As far as I know the weapons fields in the baltic sea and the north sea are very big and 2 years ago I heared a discussion about the dangers specialy in front of the coast of Belgium and some experts believe any big storm can breack some of thies weapons and a gas could cloud that get to the surface and kill some thousend of people.
The places are well known as well as the problem. In Bornholm (Denmark) in the baltic sea the fishermen have special intructions to follow when they catch some dangerous "catch" like yellow "rocks" from old chemical weapons. In the baltic sea some of these field are being cleaned because of the construction of the gas pipeline.
Until no accident occur nothing will happen,
out of sight out of mind.
Best wishes
Juergen
