Hope fading for trapped miners
Rescuers delayed by a broken drill bit for 18 hours worked through their second night in an attempt to reach nine miners trapped underground in a flooded mineshaft.
With the delay, rescuers were increasingly afraid hypothermia would set in before the men could be reached, which would not be before dawn Saturday at the earliest.
Officials believe the men have been huddled in the dark in a 4-foot-high passage, soaked by cold, rushing water.
Crews struggled to get the broken 1,500-pound bit out of the 100-foot-deep hole and install a new bit rushed in by helicopter.
They also started digging a second shaft near the 240-foot-deep shaft where the men had been trapped since Wednesday night.
No clear signal from the miners had been heard since midday Thursday.
Rescuers twice tried to listen for the men Friday, but noise from rescue equipment made it too difficult to hear if the men were making tapping sounds or other noises.
