21 November, Uttarakhand, India

Forty-one workers were trapped in a collapsed road tunnel in northern India and were there for 17 days. The number of trapped workers was revised up from 40 to 41, according to Anshu Manish, a director at the National Highways and Infrastructure Development Corporation Limited, an agency overseeing the rescue. A new drilling machine was required to be transported to the site to replace a damaged one to help with the extrication. Reports say the exceptionally hard rock formation in the area coupled with the clearing of debris damaged the original machine and paused rescue efforts after several days. All 41 were eventually rescued after 17 days trapped in the tunnel by use of the drilling equipment, a small tunnel that was drilled for the rescue and a rope and pulley system.
