What happens when tragedy strikes in the outdoors? It's a possibility we all have to reckon with when we head out on an adventure. But few of us ever experience it. 

In this special episode, New Zealand caver and explorer Kieran Mckay opens up about one of his darkest days. On May 20, 1995, Kieran and his friend Dave Weaver performed a deep cave dive in the Pearse Resurgence, near Nelson. They were pushing the limits of what was possible at the time. 

At the deepest point, Dave lost consciousness and began drifting down. Kieran was unable to save him. In this confronting episode, Kieran and Andy discuss the event, the mistakes that were made and the lessons to be learnt from this tragedy. 

Everyone who spends time in the outdoors can learn something from this episode - about safety, preparedness, emergency management, and coping with the worst case scenario.
