they're using some kind of boring machine to drill out a 16metre long tunnel for them to walk through. it's more complicated that that, obviously, but the last part of the tunnel seems to be some kind of extremely old, hard rock. they're using explosives in small amounts to break the rock apart. and it's taking for-****ing-ever.
honestly i'm starting to go a little nuts. i don't really need updates every 5 minutes on the status of the rescue operation. and every tv network is down there. it never changes "oh... they're still down there. but it's so close". just show me when they get pulled out, ffs. i don't need to hear all the minute details.
