Rescuers watched from a small monitor as the trapped workers appeared on the screen, seen for the first time since the disaster and many wearing their hard hats, as preparations continued to start vertical drilling to pull them out.
Rescuers on Monday (November 20) pushed through the new pipeline to deliver cooked food to 41 workers. The men have been stuck in the highway tunnel in Uttarakhand state since it caved in early on Nov. 12 and are safe, authorities said, with access to light, oxygen, dry food, water and medicines already being sent by a smaller pipe.
Authorities have not said what caused the 4.5-km (3-mile) tunnel to cave in, but the region is prone to landslides, earthquakes and floods.
