are some questions about that crew. and led by that captain. and you know, a ship has many compartments with hatches that are water tight and air tight. and so decisive quick action, correct action, when things went wrong is what would have saved many lives, right, leading to a proper evacuation, but also making sure the air compartments are air tight and water tight. and to the extent that occurred there could well be air pockets and people have been known to survive for quite sometime in very deep water in these air pockets. >> yeah, the most recent example, striking example, last winter, there was a chef on board a nigerian ferry that lived for three days. >> that is right, he lived for three days. so essentially there are three main things for people that survive the actual capsizing of the ship. three dangers, one is the temperature. if you're in the cold water you're not going to last for very long.
