The Indian Air Force (IAF) continued its support in the rescue efforts for workers trapped in a partially collapsed tunnel in Uttarakhand's Uttarkashi district. According to officials, a total of 36 tonne of critical equipment were airlifted using a C-17 and two C-130J Super Hercules transport aircraft. It was reported that rescuers made a significant breakthrough by pushing through a six-inch-wide pipeline amidst the rubble of the collapsed tunnel. This development is expected to facilitate the supply of larger quantities of food and potentially allow for live visuals of the 41 workers who have been trapped inside for eight days. Until now, a four-inch existing tube had been utilised to provide oxygen, dry fruit, and medicines to the section of the tunnel beyond the collapsed portion of the under-construction Silkyara tunnel on the Char Dham route in Uttarakhand. The IAF has been actively involved in transporting heavy machinery to aid the ongoing rescue operations at the tunnel site. In a statement, the Indian Air Force affirmed their continued commitment to the rescue operations, mentioning that another 36 tonne of critical equipment were airlifted on the mentioned day. The IAF's Humanitarian Assistance and Disaster Relief Operations (HADROps) are set to persist until all the required equipment is successfully delivered. The official communication from the Indian Air Force was shared on social media platform X, where they posted, #IAF assistance for the rescue operations at Uttarkashi continues unabated. Employing a C-17 and two C-130 J aircraft, the IAF airlifted another 36 tonnes of critical equipment today. IAF #HADROps will continue until all the equipment is delivered. Accompanying the statement were images depicting the loading of critical equipment into an IAF aircraft. IAF officials had previously announced on that a C-17 transport aircraft had been utilised to airlift nearly 22 tonne of critical equipment from Indore to Dehradun.
