I understand that people take pleasure in doing this sport because it&#x27;s physically challenging and they find the challenge exciting.<p>&gt; more than 11 hours after setting off on a dive that was supposed to take five hours.<p>I mean this is just insane. I can&#x27;t even imagine trying to do something in which any mistake could instantly cause my death for 11 hours straight.<p>&gt; &quot;There are lots of questions - the original questions - about where the cave goes, and where the water comes from, and they are still there,&quot; he says. &quot;And I am not afraid of the cave.&quot;<p>I appreciate this attitude, but I&#x27;m wondering if it would diminish the sport at all to have autonomous vehicles explore the cave before a dive.<p>It doesn&#x27;t remove the physical challenge of the sport itself, but it could help divers prepare for tough portions of the dive.<p>e.g. at 110m depth, narrow passage. Single file proceeding with X minutes budgeted for issues.
