2010 Copiapó mining accident steel rescue capsules, dubbed "Fénix" (English: Phoenix) were constructed by the Chilean Navy with design input from NASA. The navy incorporated most of NASA's suggestions and produced three rescue pods: "Fénix" 1, 2 and 3, all enhanced versions of the Dahlbusch Bomb used for mine rescue. "Fénix" 1 was presented to journalists and the miners' relatives for their assessment. The eventual capsule used to rescue the 33 men was the "Fénix 2", a device in diameter, narrow enough to avoid hitting the sides of the tunnel. It had retractable wheels to allow for a smoother ride to the surface, an
2010 Copiapó mining accident San Jose Mine were around 20% higher than at other Chilean mines due to its poor safety record. The collapse occurred at 14:00 CLT on 5 August 2010. Access to the depths of the mine was by a long helical roadway. A group nearer the entrance escaped, but a second group of 33 men were trapped deep inside. A thick dust cloud caused by the rock fall blinded the miners for as much as six hours. Initially, the trapped miners tried to escape through ventilation shafts, but the ladders required by safety codes were missing. Luis Urzúa, the duty shift
