John Mawson returns to the podcast after successfully launching his "Unsinkable" project with partner Misha Crosby. Unsinkable follows the adventures of the 16 surviving crew members of the San Demetrio, a fuel ship abandoned on a North Atlantic convoy crossing in 1940 after being attacked by a German "Wolf Pack."

After floating at sea for several days and nights, the crew was left with no choice but to execute an audacious plan: reboard the vessel, extinguish the fire, then heroically repair the ship enough to limp through rough seas and U boats into western Scotland, navigating without charts or instruments. The 11-episode series stars Brian Cox, Thomas Brodie-Sangster, John Malkovich and Nathalie Emmanuel.

Mawson worked on this project for more than a decade before bringing it to life. The Ojai resident talked about his own career at sea as a navigator, the Age of Exploration, his own dauntless probably ancestor Douglas Mawson, his future plans for this project as a TV series and what's next for him.

We did not talk about the Atlantic Overturning Meridonial Overturning Circulation, Senegalese hip hop or Dolly Parton.
