Chile rescue: engineering par excellence

Thirty-three miners were almost a kilometre down deep in earth's bowels. Some earth movement caused a section of the tunnel to collapse, trapping them in. Efforts to find out if there were survivors were made.
Something akin to a miracle occurred. When sinking long holes in a rather try and error manner, then retrieving to see if anything--just anything--got on the drill tip. At one such time, a piece of paper was wrapped on the drill bit. Unfurling it, and there was a note written on it. The information was sufficient to launch a flurry of activities that culminated into the thirty-three miners rescue earlier this week.
The challenges to engineers were daunting. At some 700 metres below the surface drilling a hole capable of lifting the men to safety was a mammoth-sized problem. That was when the world noted the special position of engineers for mankind. So long have they floated in the oceans with thousands of tons of freight, or cruising high in jumbo jets; taking it for granted that the craft are just there, not observing the fantastic engineering of them.
I take this opportunity to salute all involved in the rescue operation, and kudos to all the people of Chile for the miracle.
