Free at last

The ships that have been stuck in the ice in Antarctic are finally free and moving through thinner ice.  A Russian ship with scientists, crew, and other passengers got stuck in the thick ice and had to be rescued.  A Chinese ice breaking ship came to their aid but couldn't reach them.  They got stuck in the ice after using their helicopter to transfer the passengers to an Australian ship.  The US Polar Star was on it's way to help but has been released since the two ships have begun to move on their own.  rescue complete
