Now, to the latest on the miracle survival story we told you about on tuesday. Brand-new video of the moments just before that 19-year-old fishman was rescued after surviving more than 24 hours in icy alaskan waters. He's speaking out now. And abc's john muller is here with that story. Good morning, john. Amazing he can speak. Reporter: It is amazing. This story just gets better. The details are astounding enough. But this morning, we hear from the courageous teenager who refused to die. We also get a firsthand look of the gripping video the moment this nightmare ended in triumph. Easy right. Reporter: The coast guard video shows a desperate 19-year-old ryan harris, in the ocean, alone, moments before his rescue. Hold position. Reporter: Plucked from the frigid alaskan waters saturday, after 24 hours of drifting, kept afloat by this plastic fishing crate. I cried a lot. I wanted to see my brother and my mom. Reporter: Harris says the all-day and night ordeal was when a giant wave flipped his fishing boat. The bow was up in the air. Reporter: Onboard with him, his friend, 40-year-old stoney matt huffman. As the boat began sinking, huffman screamed for harris to get inside the container. I managed to get in. I couldn't manage to get him in. He let go of the tote. And the waves pushed us apart. Reporter: All alone, harris drifted, not knowing what happened to his friend. I was emotional distraught once I sat down. Reporter: Huffman was alive. He found a suit like this. As the boat sank, he grabbed on to the lid of one of the fishing bins. He began swimming to shore and made it. But harris was still floating in the alaskan sea. Three hours after the boat flipped was probably the hardest time because that's when i started crying my eyes out. I just really missed my family. I was almost at 50/50 at that point. Either I'm going to make it or I'm not. Reporter: To keep sane, harris says he sang songs like "rudolph the red-nosed reindeer." And he kept repeating this mantra. I'm ryan harris. I'm not going to die here. Reporter: And he didn't. When I saw that helicopter coming to pick me up, I was really ecstatic. I'm going to go home and get a slice of pizza. Reporter: He deserves that. The biggest challenge for harris was to balance that plastic bin in the waves. Imagine doing this for 26 hours. He had a cut on his head, mean blisters on his hands from clutching on so long. But otherwise, doing just fine. The waters were so icy. He had to be miserable. But he got a slice of pizza. Hope it was a good slice.
