One puzzle about the Chilean rescue
Discussion
There's a video of the last rescuer leaving the Chilean mine after the heroic rescue on the BBC here. A magnificent effort but I did wonder, who or what causes the camera to wobble 4 seconds in if he's the last to leave? Just seems a bit odd...

Chile has had a hard time recently, With the earthquake and other thing's so this is at least something for them to celebrate .They are national hero's for bringing the country together ,whilst surviving the most horrible situation of being the only Humans to ever spend that much time recorded underground.

I'm not saying I'm not pleased for them and their families, but if I was one of the drilling team who'd just dug an inch-perfect shaft to rescue them in a fraction of the time expected, I'd be somewhat fked off with the guys who sat on their arses waiting for me got all the hero accolades!

My puzzle - how on earth did the rescuers get that hole so damn accurate?!
GPS is all well and good, but there isn't any underground...!
They would have taken directional surveys as they drilled to record azimuth and inclination.GPS is all well and good, but there isn't any underground...!
They would know the location of the subsurface safe zone and used that as a target centre.
From the surface location you can derive a path to drill to the target.
