While the goal of transferring 1.3 million gallons to Nome was successful, there is still a long journey ahead for the ships and crew before their mission is really over.
"I don't really feel like it is over yet until everybody is safely through the ice," said Jason Evans, board chairman of Sitnasuak Native Corp., the corporation that arranged for the tanker delivery.
Evans called the transfer of the fuel "a huge milestone" but said the mission was not over. The tanker and icebreaker still need to get out of the frozen ice and back home, he said.
The plan is for the icebreaker to help get the tanker back through the ice and to open water where the tanker will head for Russia. The icebreaker will go to Dutch Harbor, Alaska to drop off supplies and then to its home port in Seattle.
