Yeah it's not looking good as they have like 10 hours tops of air left now? If the sub has not imploded, it'd be the waiting and knowing that'll weigh so damn heavy in such a confined space. Especially knowing the pressure just outside the tub.This way out would be so lightning quick, you'd never know what happened. But yea, No subs, No cave diving, plus my fear of deep, dark water, The hell with all that. I hope...these people come back but, I just dont know if its even possible at this point.
