Men rescued after 13 hours trapped in sub
Divers have rescued two men who were trapped in a submarine rescue vessel off the coast of Perth.
The Australian Submarine Rescue Vehicle (ASRV) was conducting a certification trial about 15 nautical miles west of Wanneroo when one of the cables attaching it to the mother ship snapped.
The vessel was lowered 130 metres to the sea floor, where the men remained for almost 13 hours.
The secondary cable attached to the mother ship was used to winch the vessel to just below the surface, where divers swam down and brought the men to the surface.
The two men are receiving medical treatment
Can anyone explain why the sub was winched to just below the surface and then the divers brought the two submariners out?
