What grabbed their attention was the fact that the object managed to manoeuvre the tricky mountain slope with amazing ease.

"It was like a head made of balloons, with a body that had no arms. The four-foot long object even started changing colour from white to black, as the sun shone on it," recalls Kulkarni.

"But as soon as we got nearer, it stopped, turned, changed back to its white colour, rose in the air and then beat a hasty retreat and disappeared."

"It could not be a weather balloon because it went against the wind direction. We also contacted robotics laboratories but have not found any man-made machine that manoeuvres such complex moves.

Neither can we co-relate it with the existing technological devices or with unmanned spy machines," says a perplexed Kulkarni.
