we're rejoining now with michael krye who has spent decades working on maritime safety issues. he was a spokesman for the cruise industry and is a former coast guard officer. let's talk about the rescue, michael, if i can. was this the safest thing just to have the tugs bring the ship to dock even though it took four and a half days? >> yeah. i really do believe so. obviously they could have taken passengers from one ship to another but then the other ships would have been at over capacity. and also the process of actually physically moving people from one ship to another in the middle of the ocean is a difficult process. so the carnival corporation, carnival cruiselines, took the judgment and probably a good judgment that the best course of action was to bring them home. while they were on board the ship. now, nobody -- nobody is discounting the fact that it was a horrific voyage. and i think carnival has repeatedly apologized for that. but they were brought home with no loss of life and no significant injuries. >> okay. i want to go back to what we were talking about before i
