The coast guard requires an abandon ship drill before departing.... a laugh. 3000 passengers and crew leaving ship. If the ship lists one way or the other, you lose half your lifeboats. An aircraft carrier has the same amount personell, do you see lifeboats a hanging??? No, when you abandon ship, you jump off(they teach you in boot camp). Those special need people are sunk chickens as it ain't like Titanic...it is going to be a dog eat dog rush. Me I will grab my lifejacket and my naval training will take over.
