Air Chief Marshal BS Dhanoa on Saturday visited the air force station in Jorhat, where he was briefed by senior officials about the ongoing search and rescue operation. “Air Chief Marshal Dhanoa was given a detailed briefing about the operations and was apprised with the inputs received so far,” an Air Force spokesperson said.
