Is there any evidence that Alta was operational? Last time she moved under own power was 2012. She was towed to the scrapper. If could have moved herself, then they could have saved the cost of the tow. It doesn’t make any sense that would use ship was bound for the scrapper. They would have to fix the engines and half the other stuff wouldn’t work. People would have noticed ship that never moved moving. There are working ships that could have done the job.
