Drill breakthrough raises hopes for trapped Chilean miners
Rescuers drilling into a cavern where 33 Chilean miners are trapped have completed a bore hole ahead of schedule raising hopes the men could be out earlier than expected.
The 12-inch-wide drill guided by a pilot hole half its diameter reached 2,070 feet beneath the surface, puncturing the top of a passage near the chamber in the San Jose copper and gold mine where the men have taken refuge.
