Um, tonight, a glimmer of hope for the 41 construction workers trapped in a collapsed tunnel 3 miles into the Indian Himalayan mountains. Authorities releasing heart wrenching footage of their first visual contact with the men after more than a week of grueling rescue efforts.

Yeah, Bishop.

About a dozen people can be seen throughout the footage, and an official can be heard telling the men, we will reach you all soon. Don't worry. According to a government spokesperson, food has been delivered to the trapped workers through a small pipe constructed by rescuers, and oxygen is being delivered through a second one. Heavy machinery and international teams have been brought to the remote area to help construct a larger pipe that would be wide enough for the workers to crawl out. But first, teams have to drill through 195ft of debris. On Friday, operations stopped after a machine broke down and rescuers feared the entire tunnel could collapse.

This is still an extremely dangerous environment, so we're making it safe for the rescuers in there as well.

This area, Uttarakhand, is known for its Hindu temples and has recently seen constant construction in order to accommodate the spike of pilgrims and tourists. The tunnel that collapsed is part of a federal project hoping to connect Hindu pilgrimage sites. But now, some experts warn the continuous projects could be taking an environmental toll on the region.

The Himalayan region is very, very fragile. That means we must reevaluate all the projects that is going on this moment.

What changes need to be made to make sure something like this doesn't happen again?

All the construction activity must pass through international standard of safety. We must reaccount climate change into the process of planning and management.

As of Tuesday, rescuers seem optimistic and say they expect a breakthrough within the next two days. This man's brother is one of the workers trapped. He says he is feeling more relieved and confident his loved one will make it to safety. Ellison Barber, NBC News.
