Richard: Got a very positive feeling about today. The conditions are improving. Lots of sharks around, come to, close to the boat. I think they're inviting us in. Narration: But filming a successful strike from underwater required a different strategy. No longer worried about being hit from below, Richard and Doug opted for the quieter approach of snorkelling at the surface, only going under at the final moment . Would this new technique work? From the surface, the signs were good. and John was once again following the action from his platform. So, how did it go for Richard? Richard: Unbelievable! That happened in a second! It was out of nowhere! Doug: My first hint that something was happening was when I saw a bunch of bubbles around the bird. Then, I could kinda see the shape of the shark. Richard: That is the most astonishing thing I've ever seen. Narration: But there was more to this story. Richard: You know, you've got this incredible predator who's lurking around and you know he's out there or she's out there. You know this animal is circling you. You can't see it, it can see you. And so, you can't help now and again just to look away for a second, and in that split second on this occasion that I looked away, the shark hit. The power of the animal as it took the albatross was on the one hand terrifying, but on the other hand completely transfixing. I think that shot's going to haunt me for the rest of my life Narration: Richard may only have filmed half the strike, but in the end, given the nervousness of the sharks, he was lucky to get even that.
