I can't imagine there was any real confidence that given previous video of the fuselage that it could be raised intact as there was no apparent remaining structural integrity.
There may have been, the first time around. That right wing looks nothing like the original video, which appeared to show the top surface mostly intact. The latest video shows nothing but internal structure. I wonder if one of the previous "recovery" attempts included rolling that wing over the ship's stern?

On this page one can get a good idea of the challenging diving conditions, including swells of less that 1 foot and water clarity that really cannot be expressed as being similar to whale poop. Great video on that page as well.
