As far as I can tell I think the company involved hasn't released a passenger list.
edit: An earlier version of the BBC's article said it wasn't known if people were on it at all; clearly there were, but I'd bet this is why the headline is so unclear.
I see. Regardless it sounds like it was unmanned because of the deëmphasis on the missing passengers. It's like saying “missing car” when people that were in a car go missing.
