You got me and I stand corrected.
From the article, they have up to 96 hours to conduct a rescue:
"Time is a factor, officials said. “In terms of the hours, we understood that that was 96 hours of rescue or emergency capability from the operator,” Mauger told reporters. “And so we anticipate that there’s somewhere between 70 to the full 96 hours available at this point.”"
The point about the number of days I got confused from when the ship left port. The route down is actually just a couple of hours.
Sorry about that.
