Boys continue diving training as concerns over health emerge

How about they prepare a drill rig onsite and drill a "pilot" hole and they can better estimate how the ground is for drilling a big hole. 600-800 metres in lime stone should not be a big problem these days.

Also as a bonus it will give access to a good air supply just  in case it is a long wait in there, brought on by illness or water problems.

Are you a bit slow? They have been drilling for days. The difficulty is estimating where to drill.

The question is....how did they get 5k into the cave?

The area where they are now is near what is known as Pattaya Beach.  Those familiar with the cave say it is most likely to remains dry when the rest of the cave system floods.   Once they realized they were trapped, it was the logical place to try to get to to wait out the flood. 

This was known to the rescuers and it was their objective to get there to try to locate the lost hikers since this was the most likely place where they could be found alive.

Uber, Tuk Tuk or Grab taxi maybe? If you read the story and you will find out that it wasn’t flooded when they entered 

Wow...I did not know that Uber/tuk tuk/taxis drove into caves with parts so narrow that person had only enough room to literally crawl through and scale walls to get to the next passage... you sir are a genius....thanks for the enlightenment...

I really can't, understand why nobody has suggested using oxygen rebreather's. The apparatus is small and, light and the tanks are small too. They would hold enough oxygen for over two hours use. There would be no air bubbles which could affect any visibility. They are normally not used for the diving because oxygen is toxic at over 30 feet depth. But water in the cave is very shallow, so there would be no problem.


The problem isn't the equipment available, per se, although there is one place along the extraction route where the divers need to take the tanks off in order to navigate a small opening.  (I don't know if a diver with a rebreather would fit thru it) 

The main problem is the strength, and direction, of the water currents,.  The experienced rescue divers, who presumably are reasonably strong swimmers, are needing to use ropes to pull themselves against currents on the swim out.   Reports say none of the children know how to swim (and of course they have no experience using diving gear in dark, tight conditions).   It is reasonable to take some time getting them prepared for the ordeal.

The current situation here is to try to pump out as much water as they can before the levels begin to rise again.   The more they can lower water reduces difficulty of the the extraction.   As long as the pumping is reducing the water level, then the best option is to wait in place and take advantage of the time to train up the kids, stock supplies, and prepare guide ropes along the route. 

The time to assess progress and decide if a swim out is viable will be when the re-fill rate begins to exceed the pumping drain rate.  (or when weather forecasts indicate that this is imminent.)

We have offered a commercial/military solution that will take multiple stage SRP systems with ex-military, now commercial divers and commercial diving systems. It may also not be 100% fail safe, but likely is.  To continue on as a SCUBA rescue, blood on your hands is guaranteed from the info we can see.  The offer is still out there.

Frankly, I just can't understand how or why the group, apparently led by their coach, would have felt the need or desire to travel so far into this underground labyrinth.

Maybe they got lost and thought it was the way out.

Have never read anything about a drill phase. there are radio/sonic transmitters that if deployed inside on site will pin point where to drill.

They could easily bring in an oxygen tent, where they could exercise in & sleep in.

If they still do not have wire supplied electricity someone is remiss.

The hygiene situation " should "have been sorted on the first rescue day,

Medication, special minerals & vitamins can be administered .

Let's have no more loss of life because "someone"  says, get them out

Whats an SRP. ?

Why can't they use dynamite ?

 

In the old days miners drilled holes into the rock and packed them with dynamite , then they would be able to open the tiny passages. 

 

 I guess there are some risks by using this method , but it seems to me every method they choose to follow can be risky .

And you obviously aren’t even close to being a genius, you can’t even understand a joke comment. You must be a real hit at parties.

"positive action combined with positive thinking results in success"

Not your mantra is it? ?
 

Guess thats what the US thought in Vietnam. This isn't rainbows and lollipops time. I dont profess to have the knowledge or level of expertise of those that actually are on site do but I am sure if they thought it was feasible it would already be being discussed. What's your level of expertise as far as cave diving rescue goes? Or do you just cross your fingers click your heels and think there's no place like home... keep your mantras for a seminar buddy this is the real world. Clown

Obviously I am a bit slow ? 

Please enlighten me with a link to where you know this "fact"

They have since been trapped on a muddy shelf at Noen Nom Sao, which is about five kilometres from the mouth of the cave

They just can't get the distance straight, as though a kilometer or so is a trivial detail. I've seen 2 - 3km, 6km and now 5km. Anyone for 4km?

I believe this is exactly what Mr SpaceX is going to help with!

I just saw 4km in another report. Regarding round trip time for the rescue divers - I've seen everything from 3 hours to 10 hours (5 hours each way) and more.

I have a feeling this operation is being hindered by a "too many cooks" problem without sufficient organization - too many people running around in a haphazard fashion. We can't even get solid information about what is actually going on....

 

For example, many reports are stressing that the air quality is dropping in the cave to as low as 15% oxygen. Other reports, by British divers, are saying that the air quality in the cave is OK. Others are reporting that airlines have been installed.

 

Some reports stated that telephone lines had been installed. Others said they are in the process of trying to install telephone lines. If they are going to install phone lines, they had better be careful where they lay them as the divers could easily be entangled in them. One report mentioned that someone tried to dive in with mobile phones, but they got wet. Who would believe a mobile phone can pick up a signal 1km below the surface in the mountains?

Well I couldn't do any of that  $ h iT , they would have to drug me or knock me  clean out, I would be freaking out if in a tight spot thinking could get stuck and drown - no thanks.

 

I just hope they all get out safely and no one else gets injured or worse...

 

Godspeed!

Let's see. 2 - 3 km= 2.5 now + 3 + 6 : by 3 = 11.5. Divided by 3 = 3.8333333333333 km. Agreed.

That's exactly what one of the divers recommend...i agree...mild sedative...less drama

Got your "answer" now work backwards?

The time to take them out is when the cave diving experts say it is safe and not before.

ah... I think clearly we are in a much better position to determine the best time

A terrible situation for all. But only those in-charge with specialist advice (some of that may be conflicting) can make the decision.

 

Get them out now, if they can, and risk some loss of life, or leave them in the cave for a longer period of time and still risk some loss of life. :sad:

 

Damned if you do and damned if you don't. Finger pointing and blame will happen , either way. 

 

Maybe the King can make the decision on advice of the Government because he will be immune (I think/hope) from any repercussions.

So is uncle Tu with his blanket amnesty!
