CHENNAI: At 1pm on Wednesday, as a National Disaster Response Force mountaineer rappelled down the 1,000-foot tall Kurumbachi hill to rescue injured trekker R Babu, it was drones from Chennai that helped him navigate the precipitous slopes.
Around 48 hours earlier, while on a hike with friends, Babu had fallen into a crevice on the side of the hill in Malampuzha, near Palakkad district in Kerala. The friends tried to pull him up with sticks, but failed and sought help from the police, who then roped in the army.
