LONG WARNED THAT THE SUB WAS NOT CERTIFIED TO DIVE SO DEEP. >> JOINING ME NOW, THE HOST OF DISCOVERY CHANNELS EXPEDITION UNKNOWN, JOSH GATES, HE TURNED DOWN A TRIP TO THE TITANIC ON OCEANGATE TITAN SUBMERSIBLE DUE TO SAFETY CONCERNS. THAT IS THE VESSEL THAT WAS LOST THIS WEEK. AND DAVID MARKEY, RETIRED U.S. NAVY CAPTAIN AND SUBMARINE COMMANDER. HE IS A BESTSELLING AUTHOR OF TURN THE SHIP AROUND, AND LEADERSHIP HIS LANGUAGE. DAVID, YOU AND I SPOKE ON MONDAY NIGHT. AND THIS IS THE OUTCOME YOU EXPECTED. WHAT HAPPENS NOW? >> NOW I THINK THAT THEY ARE GOING TO TRY TO PICK UP SOME OF THE PIECES OF THE LITTLE ROVERS THAT THEY HAVE. AND BRING THEM UP TO THE SURFACE PUT THEM BACK TO GATHER. AND WE NEED TO DO AN ANALYSIS ON THE VESSEL TO SEE EXACTLY WHERE THE FAILURE WAS THAT CAUSE THIS IMPLOSION. THE HULL OF THE VESSEL, THE MAIN PART IS MADE OF THREE DIFFERENT MATERIALS. THE CARBON FIBER SLEEVE, THE -- , AND -- AT THE END. >> JASON WHAT ARE YOU THINKING TONIGHT? >> FROM MY PERSPECTIVE, LOOK, FIRST OF ALL I AM STILL STUNNED BY THE OUTCOME HERE. I THINK LIKE MANY PEOPLE, IT WAS ALWAYS IN THE BACK OF MY MIND AS A PROBABLE OUTCOME HERE. BUT I REALLY DID HOLD OUT HOPE UNTIL THIS AFTERNOON. AND MY HEART IS BROKEN FOR THE PASSENGERS ABOARD, AND FOR THEIR FAMILIES, A REALLY DIFFICULT SITUATION. AND I THINK A LOT OF QUESTIONS NOW THAT NEED TO BE ASKED AND ANSWERED IN THE COMING WEEKS AND MONTHS ABOUT THIS PLATFORM, AND ABOUT HOW IT WAS BUILT. AND FUNDAMENTALLY, HOW SAFE IT REALLY WAS. >> YOU FELT THAT IT WASN'T, JOSH, YOU HAD THE OPPORTUNITY TO GO ON THIS VESSEL WITH THIS COMPANY AND YOU CHOSE NOT TO. TALK TO US ABOUT THAT. >> I WENT UP HER OCEANGATE HEADQUARTERS IN WASHINGTON. I SPENT SEVERAL DAYS UP THERE WITH STOCKTON AND WITH OTHER OCEANGATE EMPLOYEES AND ENGINEERS I TOOK A RIDE IN TIGHTEN, IN 2021, JUST A FEW MONTHS BEFORE TITAN WAS GONNA TAKE ITS FIRST GROUP OF PASSENGERS DOWN TO THE TITANIC. AND IT HAD JUST COME BACK FROM A PRESSURE TEST ON THE EAST COAST. AND WE WENT TO A FUTURE SOUND, AND, LOOK, THERE ARE ELEMENTS TO TIGHTEN THAT WERE VERY IMPRESSIVE WHEN YOU FIRST WALK UP TO THE SUB. IT IS A VERY LARGE VEHICLE FOR THIS KIND OF A MISSION, MOST OF THE SUBS THAT GO DOWN TO THE TITANIC ARE TWO AND THREE PERSON. VERY CRAMPED SUBMERSIBLES, PEYTON HAS A NOVEL DESIGN. SO IMPRESSIVE WHEN YOU FORESEE IT. AND A VERY UNIQUE DESIGN. BUT FUNDAMENTALLY, IT IS SO LARGE BECAUSE IT IS MADE IN A VERY NOVEL WAY. IT IS MADE OF THIS CARBON FIBER, AS A OPPOSED TO HAVING A PRESSURE HULL BUILT OUT OF TITANIUM. AND THAT CARBON FIBER IS THE REAL QUESTION MARK HERE, IT CERTAINLY WAS FOR ME. THERE IS VERY LITTLE DATA ABOUT HOW THAT MATERIAL IS GOING TO BEHAVE AND THE KIND OF PRESSURE CYCLES IT WAS GOING TO BE PUT THROUGH. AND THE KIND OF TEMPERATURES IT WAS GOING TO BE EXPOSED TO. AND THERE WAS SIMPLY NOTHING TO BENCHMARK IT AGAINST. AND SO, THE MORE TIME I SPENT IN TITAN AND TALKED WITH STOCKTON RUSH, I COULDN'T GET COMFORTABLE WITH THE FACT THAT THERE WAS ALMOST NO WAY TO ASSESS THE RISK OF THE VEHICLE. IT WAS IMPOSSIBLE. >> DAVE IT HAS BEEN AN AWFUL FEW DAYS AS PEOPLE HAVE FOLLOWED THE STORY. AS FRIENDS, AND FAMILY, HAVE WAITED IN PANIC. THE NAVY NOW SAYS IT DETECTED SOUNDS CONSISTENT WITH AN IMPLOSION SHORTLY AFTER THE SUB WENT MISSING. AND TOLD THE ONSITE COMMANDER, WHAT DO YOU MAKE OF THAT? WHY ARE WE ONLY LEARNING ABOUT THIS NOW? >> I DON'T KNOW ABOUT THAT. IT SUPPOSEDLY TOP SECRET. BUT I CAN TELL YOU THAT AN IMPLOSION LIKE THIS WOULD BE VERY LOUD, AND AN UNUSUAL SOUND IN THE OCEAN AND THOSE DEEP SOUND CHANNELS, IT'S VERY DENSE, IT'S VERY COLD WATER. AND IT REALLY CARRIES SOUND A LONG, LONG WAY. 1000 MILES, OR 1500 MILES. SO THAT NOISE IF YOU'RE LISTENING FOR IT? YOU COULD HEAR IT A LONG LONG WAY AWAY. >> I DON'T KNOW HOW TO ASK THIS THEN. DOES IT GIVE YOU COMFORT? ON IMPLOSION LIKE THAT, THAT THEY WEREN'T IN THERE FOR DAYS SUFFERING AND FREEZING? >> MY EXPECTATION IS THAT AT THAT PRESSURE THIS WOULD HAVE BEEN AN INSTANTANEOUS FAILURE, THEY PROBABLY NEVER EVEN REALIZED SOMETHING THAT WAS AMISS. AND THEN THEY WERE GONE. AND FOR ME, WHEN WE WERE AT SEA, THAT'S WHAT WE WANTED IF WE WERE GOING TO GO DOWN. SITTING ON THE BOTTOM FOR FIVE DAYS, SLOWLY ASPHYXIATING YOURSELF AND DYING OF CARBON DIOXIDE POISONING? THAT IS MUCH, MUCH WORSE. >> JOSH, WHAT DO YOU SAY? >> I ECHO THAT, I CERTAINLY DO THINK THAT IT IS STARTING TO LOOK LIKE A MASSIVE, CATASTROPHIC FAILURE THAT HAPPEN ON THE WAY DOWN. AND IF THAT IS THE CASE, THEN IT WOULD HAVE HAPPENED EXTREMELY QUICKLY. THE KIND OF PRESSURE THAT WE ARE TALKING ABOUT HERE IS MONUMENTAL. AND LOOK, PERSONALLY I KNOW TWO OF THE PASSENGERS ABOARD. I KNEW STOCKTON RUSH AND I KNEW THE HARDENING FROM THE EXPLORERS CLUB. THIS IS SUCH A SITUATION. AND AS I SAID A FEW TIMES, ALREADY TODAY, I REALLY DO HAVE A GREAT AMOUNT OF ADMIRATION FOR THE PASSENGERS ABOARD. AS ANYONE WHO HAS BEEN IN A SUBMERSIBLE CAN TELL YOU, IT TAKES A LOT OF COURAGE, A LOT OF THE TREPIDATION. WHETHER IT IS ON TITAN OR ANY OTHER PLATFORM. AS A CIVILIAN TO GO DOWN AND GO TO THE STEPS, AND TAKE ON A MISSION LIKE THIS. SO MY HEART REALLY BREAKS FOR THEM, AND FOR THEIR FAMILIES. I THINK THAT WE SHOULD HAVE A LOT OF ADMIRATION AND RESPECT FOR THEM TAKING ON SOMETHING LIKE THIS. WHICH IS NOT EASY TO DO. >> JOSH YOU DO REALLY DANGEROUS THINGS LIKE THIS FOR A LIVING. HERE'S WHAT HAPPENED THIS WEEK, DO YOU THINK IT'S GOING TO IMPACT THE DECISIONS THAT YOU MAKE GOING FORWARD? KNOWING EVEN WHAT THESE FAMILIES WENT THROUGH THIS WEEK? >> YES, LOOK, RESTS ASSESSMENT IS SOMETHING THAT WE ALL DO IN ONE WAY OR ANOTHER. AND YOU HAVE TO JUDGE RISK AGAINST REWARD. YOU HAVE TO JUDGE IT AGAINST THE KIND OF RISK YOU'RE ABLE TO TAKE ON AS AN INDIVIDUAL. I THINK THAT THE TITANIC AS A DESTINATION, AS AN IDEA EVEN, IS JUST INCREDIBLY MEANINGFUL FOR SOME PEOPLE. CERTAINLY, THE PERSON WHO WAS ABOARD WAS ONE OF THE FOREMOST EXPERTS. SOMETHING HE WAS INCREDIBLY PASSIONATE ABOUT. SO PEOPLE WHO CLIMB MOUNTAINS PEOPLE WHO JUMP OUT OF AIRPLANES. PEOPLE WHO WANT TO GO DOWN TO SEE TITANIC. AND I DON'T BEGRUDGE ANY OF THEM THEIR PASSIONS. I THINK THAT FOR ME, AS FOR ANYONE, IF THERE IS SOMETHING THAT YOU REALLY FEEL IS A MEANINGFUL THANK. YOU WEIGH OUT THAT RISK WITH THE REWARD. FOR ME WITH TIGHTEN, I JUST COULDN'T GET COMFORTABLE WITH IT BECAUSE I DID NOT FEEL AS THOUGH THE RISK COULD EVEN BE EVALUATED. AND I THINK THAT THERE IS SOME BIG QUESTIONS HERE ABOUT THE DESIGN OF THIS HULL, THE MANUFACTURING OF THIS HULL, AND I THINK THAT WE'RE GONNA HAVE TO ASK THOSE QUESTIONS IN THE COMING WEEKS. >> SO IRONIC, THE
