Curved contrails shows up at some places of Sikkim

I first came to know about such types of contrails last year when in the month of November, December and January this year, series of such unheard things had made headlines in this part of the state. Contrails were reported from different part of the state. But the one contrail that was caught from a mobile phone of Suneel Dangal, my good friend from Central Pandam yesterday was something different from what was seen last year. The contrail that was shot by Suneel was something curved and fascinating than those straight lines we had seen last year. An eyewitness from Rangpo told that he first saw an object and within a couple of minute those white clouds followed. Nevertheless it is still unknown what sort of fighter planes or any other object was making a move at the sky of Sikkim.
