( CNN ) -- All the world is watching , eager to welcome those 33 miners from the pits of hell . It is a tale of courage and resilience that rivals the return of Ernest Shackleton and his men from their ill-fated voyage across Antarctica . Nearly all the credit belongs to the 33 Chilean men who have survived the ordeal . So , too , should it go to their families and fellow countrymen who have heroically rushed to the rescue . But even as we wait to see if all men make it safely to the top , it is not too early to salute the Americans who pitched in to help as well with the U.S. technology that proved so vital . After a long dry spell , it is so refreshing to see us at our best again . The U.S.-Chilean company Geotec Boyles Bros. , which operated the first drill to reach the miners , assembled help and materials from across the globe . In Western Pennsylvania , two companies long-trained by mine collapses in that region rushed to action . They had UPS ship south a specialty drill , capable of creating shafts large enough to fit the men without collapsing , within 48 hours . And UPS did it for free . Then , working with Chilean crews , Geotec 's Kansas-based partner came up with the plan to get the miners to the surface almost two months earlier than the Christmastime date originally projected . Expert driller Jeff Hart , a contractor from Denver , Colorado , was called from Afghanistan , where he was helping American forces find water , to man the machine . The 40-year-old drilled for 33 days straight , through tough mineral ore , to reach the men trapped more than 2,000 feet below . His comment after breaking through last week ? `` We got the job done . '' Read more CNN.com op-eds . Three NASA doctors have provided advice on how to keep the miners healthy , both physically and mentally . And the design of the rescue pod is the brainchild of NASA engineer Clinton Cragg . Cragg drew on his experience as a former submarine captain in the Navy and directed a team of 20 to conceive of a small 13- foot-long tube to carry the miners one at a time to the surface . All told , about a dozen Americans decamped to the desert , and many more labored from home , to rescue the miners . The display of generosity and technological ingenuity shows our finest face to the world . Our capacity for problem-solving and helping those most in need of it , sustains the faith that we can , as Hart said , get `` the job done .
