They have just pulled the seventh miner out of the ground.
What a stunning achievement. Virtually everything is being done for the first time, with equipment designed for the occasion. Everything is going as it should. And it's not just the ground-breaking (heh) engineering. The men are in remarkably good condition, and are a testament to the care that they have received while underground.
What has perhaps been the most surprising aspect has been the involvement of the politicians. The President, Sebastian Pinera, and the Mining Minister, Laurence Golborne, have been a constant presence, and have been actively involved in the operation. No doubt it will be doing their approval ratings a bit of good, but their involvement seems genuine. Contrast Gordon Brown's photo-opportunities in Iraq - staged backgrounds, managed situations and visible disenchantment by the soldiers involved.
