Doctors? Why not two or even 1 paramedic or EMT? If the doctor can get to them, then why can’t they get out?
The doctors, and the SEALS, are trained divers. The boys and their coach are not. The way in/out is flooded and likely to remain so for significant time.
I used to work with a lady who did cave diving as a hobby. It’s incredibly dangerous; several of her friends died doing it.
They can’t swim!
The children are not ‘divers’ - the water is muddy and the access routes are very narrow.
The difficulties are fully described in the article.
Cave diving is a deadly past time for experienced divers. If anything goes wrong you can’t just go to the surface. Plus you are operating at almost zero visibility in cramped passages with or against a current. It sounds like the kids are trapped in a chamber that is above the waters but the only way out is through flooded passages.
A two mile underwater swim with zero viability and tight maneuvering. There is one passage that is so small divers have to take off their tanks to get through.
A bit much to ask on a first time dive.
I am guessing the boys are in real bad shape if the two doctors are volunteering to stay till October to get them out you would think taking the kids one at a time out that this would be doable but my bet is that it is a real treacheres journey out even for underwater spelunkers with years of experience .... real heroes the individuals who found the kids.
The cave passage is flooded, in some places 16 feet. There is not enough opening for a diver with an air tank. And the boys do not know how to swim.. They are 4 miles into the cave.
