Looks like the rescue efforts are starting to get 4 kids out. Folks hurrying due to downpour overnight.
@yayqe on Twitter is probably the best follow if you want updates by the minute.
Edit: it's been 8 hours since Elon said it should take 8 hours. Hopefully there's an update soon.
5 inflatable rescue pods commissioned by Elon have already arrived in Thailand, 8 more are on the way. Manufactured by a SpaceX subcontractor Wing inflatables.
Arcata’s Wing Inflatables, SpaceX collaborate on Thailand cave rescue
These are seperate from the rigid “submarines” SpaceX is manufacturing and hopefully on the way now.
No idea if they are in use or not but Elon is trying, which is very commendable.
