This incident happened in 2004 but seems to only be getting out now. That photograph above (Robot-like airborne figure photographed by scientific team in 2004 at Samudra Tapu) is from that incident in which a 14 person team discovered a four foot tall humanoid robot walking alongside the mountains only for it to later lift off into outer space. The video is not out yet but hopefully the Indian government will release it soon. Their military is really worried about this because along with this and other events they are having problems explaining what they are seeing in this region.
They filmed a fourfoot tall robot-like figure, that walked along the valley, 50 m away from them. The humanoid object then rapidly became airborne and disappeared. The encounter lasted 40 minutes.
It was seen by 14 persons including the six scientists. Kulkarni then interviewed each expedition member separately to verify what the team had seen. Copies of his detailed report were circulated to the PMO, ISRO, the Army and several intelligence agencies. Kulkarni established his team hadn’t seen natural phenomenon. The matter, however, was buried soon after.
