Two divers killed while exploring WW II wreck

Two divers exploring the wreck of the "Goya", a WW II German transport ship, were presumed dead after they disappeared under the water 20 nautical miles off the Polish coast. The two wanted to film the exploration of the wreck together with the crew of a Polish yacht, the "Stenia". However, according to maritime authorities, none of them had any official permission to conduct underwater works, while the Stenia's crew had been licensed only for sport and recreational diving. Apparently, the two divers wanted to disentangle a remote operating vehicle from a fishing net but went down without special equipment required for deep-diving and when they failed to resurface one hour later, a rescue mission was undertaken but to no avail.
