to be used in a training video one day. minutes pass. they're prepping captain fulford. but down in the bucket, kim is starting to wonder if they'll ever be saved. >> just dangling there, i wasn't sure what they were doing. were they figuring out how to get us? were we hopeless? would they have to get us? are we hopeless? >> but now he's on his way to captain kim and the others. >> i couldn't feel him necessarily moving when he was coming down. but clearly you can feel -- we felt his weight when he stood on top of the boom. >> remarkably, despite the added weight, the bucket holds steady. finally, after just under an hour of uncertainty, captain fulford is a welcome sight to an exhausted kim books. >> okay. >> it was comforting enough to know you're okay. >> okay, but she's not on her way to safety just yet. after assessing the condition of the bucket, fulford decides bruce needs to come up first. >> we knew that individual was under more stress than the other
