Four crew members trapped inside capsized cargo ship off US coast

Four crew members are trapped inside an overturned cargo ship off the coast of Georgia, USA. 

The Golden Ray, a car carrier, capsized early on Sunday morning (local time) while en route to Baltimore. 

Authorities were alerted to the incident by a 911 call, and managed to save 20 people from the ship via helicopter before smoke and fire forced them to retreat.

Those remaining on board the 656ft vessel were deemed 'missing' until the US Coast Guard managed to make contact with them after drilling a hole through the hull.

Footage taken at the dramatic scene shows a rescue helicopter landing atop the listing ship to make contact with the trapped crew.

The four crew members, all South Korean nationals, are believed to be alive and well inside an engine room. Rescuers will send supplies through the hole in the hull while they devise a plan to get the workers out.

On Monday (local time) the Golden Ray was listing at about 90 degrees, blocking off the busy Port of Brunswick. The US Coast Guard says the capsized ship, which is carrying more than 4000 vehicles, has not released any pollutants into the water.

All other sea traffic is forbidden to come within 800m of the ship after an emergency safety zone was set up.

Hurricane Dorian hammered the Georgia coast last week, but was long gone by the time the Golden Ray got into trouble.
