The operation to rescue 41 workers trapped inside an Uttarakhand tunnel for more than two weeks now has been a story of new challenges at every corner and rescue teams tweaking their plans to meet them. The past 16 days have seen government authorities constantly fine-tune their strategies and find new approaches to bring out the men at the earliest. At this point, rescue teams are drilling from multiple directions to reach the workers. They are simultaneously focusing on ensuring their physical and mental well-being as the operation drags on.
