In case the world doesn’t know, it was AMERICAN know how, AMERICAN ingenuity and AMERICAN private enterprise that caused the miracle of the rescue of the Chilean Miners.   Schramm Inc. of West Chester , Pennsylvania built the drills and equipment used to reach the trapped miners.   Center Rock Company, also from Pennsylvania , built the drill bits used to reach the miners.   UPS, the US shipping company, delivered the 13-ton drilling equipment from Pennsylvania to Chile in less than 48 hours.   Crews from Layne Christensen Company of Wichita Kansas and its subsidiary Geotec Boyles Bros. worked the drills and machinery to locate and reach the miners and then enlarge the holes to ultimately rescue them.   Jeff Hart of Denver , Colorado , was called off his job drilling water wells for the U.S. Army's forward operating bases in Afghanistan to lead the drilling crew that reached the miners.   Atlas Copco Construction Mining Company of Milwaukee , Wisconsin , provided consulting on how to make drilling equipment from different sources work together under differing pressure specifications.   Aries Central California Video of Fresno, California, designed the special cameras that were lowered nearly a mile into the ground sending back video of the miners.   Zephyr Technologies of Annapolis, Maryland, made the remote monitors of vital signs that miners wore during their ascent.   NASA Engineers designed the ‘ Phoenix ’ capsule that miners would be brought to the surface in, and provided medical consulting, special diets, and spandex suits to maintain miners' blood pressure as they were brought back to the surface.   Drilling Supply Co., Houston , also involved.   Canadian-based Precision Drilling Corp. and South-African company Murray and Roberts, drilled  backup rescue shafts in case the American rig failed - which it did not do.   Both of the other planned drill rescues, (Plan A and Plan C) had failed, Plan B, the American drill plan, was the only one working for the ten days of the rescue effort.
