It takes real willpower to not freak out when this happens. The most common scenario is something pulls off your mask or pulls the regulator out of your mouth. Panic is the number one killer in diving, and it is amazingly easy for it to happen. Navigating through what looks like a 500-metre flooded section (if the map on CNN is to scale) would have totally freaked me out. My brother taught me to dive when I was around 13 and it wasn't difficult, but I was already a snorkeler used to free-diving to 30' or more.

Teaching kids that young to dive and navigate in a narrow tunnel in murky water with only portable lights has a very small chance of succeeding without someone dying, in my opinion.

Either way, they have days at best, not a month and a half.Ī Chilean-style drill rescue would be a wasted effort. This cave is 50% deeper under the mountainside than the mine, through poorer-quality and less-known ground, and as mentioned above there's no clear access for hole-drilling equipment to set up, so that adds even more time.Įven if they manage to get an air system so the kids don't suffocate within the next couple days, the water pumps are already overwhelmed as is, so if they aren't out by the time the rains come, they're drowned. The exploratory borehole for the Chilean miners took 15 days to drill, through 2300 feet of extensively surveyed ground to a well-mapped mine. Summarizing what Lagrange mentioned in the other thread: How quickly do you think they could stage the equipment and drill even a small pilot hole through nearly 800 meters of solid rock? The things he is proposing sound not workable. I thought Elon Musk could help with drilling the hole. I think they just need to get busy and drill a hole to bring the kids up. 2 air tank connections on front & 2 on rear, allowing 1 to 4 tanks simultaneously connected, all recessed for impact protection w secondary cap seal if leak develops.Īnd when someone asked if it had been 'Confirmed to maneuver through even the most narrow passages,' he answered 'yes.' Promoted Comments Update: In a follow-up tweet, Musk describes some features of the rescue pod.Ĥ handles/hitch points on front & 4 on rear. In a Friday evening tweet he described this option as 'less likely to work, given tricky contours, but great if it does.'

It would still be a harrowing and claustrophobic experience, but-if everything works as Musk describes-it could be much less dangerous than conventional scuba diving, where a panicking teenager could lead to the death of the teen himself as well as his professional scuba guides.Īt the same time, Musk says he's continuing to work on his earlier idea: an 'inflatable tube with airlocks' that could be inflated inside the submerged portions of the tube, creating a tunnel the kids could crawl through. The kind of tiny submarine Musk is describing could allow professional divers to bring the boys out without requiring the boys to do anything more than lay still. With heavy rains expected in the coming days, there's a danger that the water level could rise, drowning the group. On top of that, Thailand is just entering its rainy season. The oxygen level in the boys' location has been dropping.

Some of the boys don't even know how to swim, and so it might not be possible to provide them with the training necessary to swim out, even with professional help. A route that narrow is a big challenge for even the most experienced cave divers-indeed, one diver died ferrying oxygen tanks to the boys earlier this week. Much of the path out of the cave is flooded, and in places the cave gets as narrow as 70cm. We haven't seen any reaction from Thai authorities to this idea yet, but it could provide a solution to the deadly dilemma facing Thai rescuers. 'Construction complete in about 8 hours, then 17 hour flight to Thailand,' Musk tweeted just before noon, California time. Extremely robust.Īnd this isn't just a theory: Musk says that his team is building the contraption now. Light enough to be carried by 2 divers, small enough to get through narrow gaps. Primary path is basically a tiny, kid-size submarine using the liquid oxygen transfer tube of Falcon rocket as hull. He tweeted that his team was working on building 'double-layer Kevlar pressure pods with Teflon coating to slip by rocks.' A mid-day tweet on Saturday provided another update: By Friday afternoon, Musk's thinking had evolved. On Thursday night, Musk tweeted about an idea to use an inflatable nylon tube to help the kids escape. Musk has had a team of engineers working on the problem for the last couple of days and has been keeping the world updated on the work via Twitter. Elon Musk tweeted on Saturday that a team of SpaceX engineers is hours away from completing work on a 'tiny kid-sized submarine' that could be used to extract 12 teenagers and preteens who are stranded with their soccer coach in a flooded cave in Thailand.
