Engineers had planned to extend the piping nearly twice as far, but they decided to stop after the sleeve
-- the hole is angled 11 degrees off vertical at its top before plumbing down, like a waterfall
-- became jammed during a probe. Iturra said he recommended the first man be pulled out at dawn because the miners are to be taken by Chilean air force helicopters to the nearby city of Copiapo and fog tends to enshroud the mine at night. It is a roughly 10-minute flight, said Lt. Col. Aldo Carbone, the choppers' squadron commander. He said the pilots have night-vision goggles but will not fly unless it is clear. Ambulances will be ready for backup. The drive would take about an hour. Officials have drawn up a secret list of which miners should come out first, but the order could change after paramedics and a mining expert first descend in the capsule to evaluate the men and oversee the journey upward. First out will be the four miners fittest of frame and mind, health minister Jaime Manalich said. Should glitches occur, these men will be best prepared to ride them out and tell their comrades what to expect. Next will be 10 who are weakest or ill. One miner suffers from hypertension. Another is a diabetic, and others have dental and respiratory infections or skin lesions from the mine's oppressive humidity. The last out is expected to be Luiz Urzua, who was shift chief when the men became entombed, several family members of miners told the AP, speaking on condition of anonymity because they did not want to upset government officials. The men will take a twisting, 20-minute ride to the surface. It should take about an hour for the rescue capsule to make a round trip, Aguilar told the AP. Plans called for the media to be blocked by a screen from viewing the miners when they reach the surface. A media platform has been set up more than 300 feet (90 meters) away from the mouth of the hole. After being extracted, the miners will be ushered through inflatable tunnels, like the ones used in sports stadiums, to ambulances that will take them to a triage station. Once cleared by doctors there, they are to be taken to another area where they'll be reunited with the chosen family members. Next stop: a heliport and the flight to Copiapo. At the hospital, all the miners will be kept for 48 hours of observation that will begin when the last one exits the escape shaft.
