### Uttarakhand tunnel rescue

On 19 November 2023, Dix joined the Uttarakhand tunnel rescue operation. Upon arrival, Dix promised to evacuate all 41 workers safely. Dix played a leading role in the operation that saved 41 workers who were trapped nearly 200ft below the surface. He worked together with five agencies ONGC, SJVNL, RVNL, NHIDCL, and THDCL, who had encountered difficulties completing the rescue mission.
Dix suggested that the team use soft mining techniques, to avoid disturbing the mountain and causing another avalanche which would put the workers at further risk. Rescuers had been using large earth drilling machines which caused vibrations that made the tunnel more unsafe. The large drills also broke down from hitting metal obstacles from the collapsed tunnel, forcing the rescue operation to be paused frequently. Dix proposed much slower and gentle approaches that he considered safer. The rescuers used a thin pipe to carry the trapped workers to safety. They finally excavated by hand to avoid disturbing the rock and causing further damage.
Dix displayed faith during the rescue by setting a makeshift temple during the rescue, which gained attention on social media. During the rescue mission, Dix was seen praying at the temple of local deity Baba Bokh Naag ji.
