The video of a helicopter flying near the Nilgiris in Tamil Nadu and vanishing into the mist has emerged after India's top general, Chief of Defence Staff Bipin Rawat, was killed along with 12 others in a crash on Wednesday. The video, tweeted by news agency ANI and sourced from locals, apparently captures the last moments of the Indian Air Force Mi 17 V5 chopper before it crashed into the mountains yesterday afternoon. It shows the chopper flying into a mist. The Air Force has not commented on the authenticity of the video, which also shows a group of people looking at the chopper.
