I think things are being said by people who don't really understand the situation. I am one of those people but I did read that the current flow is to the exit. This was an added difficulty for the divers going in, but should assist the kids coming out. There are plenty of other issues but I don't think current is one of them.

 

 

I suspect (IANACD) that current from behind would be more of a nuisance than from in front, tending to push your body past your hands, and hands off any handholds. You could go backwards, but then you can't see where you're going.

 

 

Sounds like they can't see much due to turbidity anyway - and bright lights, like driving in fog, can make it worse due to the back-scatter). 

 

But yeah, getting pushed along when unsure what's in front would be horrible.

And when things start getting rushed, people get tired, or start to over extend or exceed hours etc, and then accidents happen...

 

Diving is hazardous enough, doing it underground in confined spaces makes it even more dangerous....

 

"Thai authorities say a former navy SEAL working to rescue boys trapped in cave has died from lack of oxygen."

Terrible news. This is exactly what everyone hoped wouldn't happen. If this can happen to an experienced diver, the boys don't have a chance.

We need more details before concluding that.

According to the BBC report he ran out of air on the way back from a dive to deliver air supplies (sounds like they are stashing tanks along the route)

 

What a nightmare.

I wonder if it was an inherent risk or someone miscalculated how much air he needed? Inherent as in ran into caving problems and took longer than expected

I wonder how many dives have been made so far all the way to where the boys are, and how many have been made to the staging points along the way. If there's been several then you'd think they'd know the timing by now. But so many unknowns, so many risks...

There is also a chance of more rescuers' lives lost than the number of lives they are trying to save.

I am lost for words. undescribably sad that someone has lost thier life trying to save others. I hope he gets celebrated accordingly.

 

I am not particularly religious however, this verse does jump to my memory.

 


Greater love hath no man than this, that a man lay down his life for his friends.

I am starting to get a really bad feeling about the outcome of this.

 

I am hoping against hope that I am wrong.

 

Sometimes these unfortunate situations serve as a timely reminder of how small my issues really are day to day.

Had a really bad feeling about this when they were missing for a week, then great feeling when they were found alive and well, now bad feeling again... Such a risky rescue - can see why they are talking about leaving them there to ride it out.

The lost rescuer, there was an air leak in his tank, so not related to the difficulty of the caves. The heavy rain is now Sunday, they are talking about sooner than later. Then they say wait a month, but I heard the monsoons stay till October. What we do know is many are involved so all we can do is know that when a call is made, its the right call. If Elon Musk's company can bore a hole even if thats for supplies that would help. And entertainment, thats crucial from a psychological perspective.

Most likely equipment failure.

Could have been but more likely miss calculation. Moving oxygen tanks would require extra exertion in what I'm guessing, is is near to zero visibility condtions. Anxiety, task loading, confined environment and zero visibility usually contributes to a higher surface air consumption rate.

Guide lines with neon lights may also be used and if he lost sight or a hold on the line it would have been difficult to remain calm when you can't even see your hand infront of your face.
