Dehradun, Nov. 2 -- The bodies of all six people killed in a helicopter crash near Jyotirmath in Chamoli district on Friday were handed over to their families after postmortem examinations at the All India Institute of Medical Sciences (AIIMS), Rishikesh, officials said on Sunday. Chamoli district disaster management officer (DDMO) NK Joshi said joint teams of the Army, Indo-Tibetan Border Police (ITBP), National Disaster Response Force (NDRF), State Disaster Response Force (SDRF) and district administration retrieved the bodies from the crash site in rugged terrain. "Through the tireless efforts of the joint teams, the bodies of all six individuals were safely brought down via a challenging trekking route and transported to the Community Health Centre (CHC) in Jyotirmath," Joshi said. "They were then airlifted by helicopter to AIIMS Rishikesh for post-mortem examinations. After official procedures, their bodies were handed over to their respective families," he added. The helicopter, operated by Trans Bharat Aviation and bearing registration call sign VT-HCX, was returning to the Sahastradhara helipad in Dehradun from Badrinath when it crashed on Friday afternoon. Officials said the accident was likely caused by inclement weather and rain, which severely reduced visibility along the flight path. The aircraft took off from Badrinath at around 1.12 pm but lost radio communication shortly after flying over the Jyotirmath valley. It subsequently disappeared from tracking systems. Rescue operations launched on Friday were suspended due to difficult terrain and fading light. An Army unit that alerted authorities about the crash also warned of Himalayan bear activity in the surrounding forest, officials said. In the wake of the crash, the Uttarakhand Civil Aviation Development Authority (UCADA) has made co-pilots mandatory for all helicopter-chartered flights on the Char Dham route with immediate effect. "Single-pilot operations will no longer be permitted for the chartered flights on the Char Dham circuit," said UCADA chief executive officer Prateek Jain. The authority has also introduced a strict post-flight reporting protocol for every trip. Under the new directives, pilots must submit a detailed log immediately after landing, documenting weather conditions encountered along the flight path, changes in visibility and any operational anomalies....
