As it was full of cars, I always thought it capsized while inbound. It happened just a week after I transited that area and I was overtaken by a similar ship and was pretty shocked at how fast they make the turn to go up the river.
Nice documentary..having been there since the beginning..there is no mention of the conflicting salvage companies..one that started and the one that finished the job.. all in all this conflict eventually added to the delay of final removal..not including hurricane seasons and Covid to the workforce..
