Respected Sir/Madam,My self Sandip Roy, I am from Kolkata. I want to send and share my experience with you it might help you in some way I think. So I just about to tell you in brief what happens just 3 days back.The Incident :I am working In Kolkata, just few days ago I came to know that I have to visit one of our customer in MP(Maddhya Pradesh) our customer is HINDALCO so without any further preparation I board a train from Kolkata to Singrauli (Shaktipunj Express) from Howrah. I couldn't sleep well in train so at night I was awake almost all the time. The incident took place at around 1:15am when I was looking through the window I saw a plane is flying parallel to our train so I overlooked it but suddenly it catch my attention when I saw strange lights coming from it GREEN, YELLOW, RED, ORANGE, BLUE all the colors are there it was just amazing to watch, so I watch it for a while The I realize amazing and horrible things. The unusual craft is moving very fast like jumping from one place to another place in seconds first it was small jumps then over time it jumps like one end of the sky to another end and then come back to the same place again then again right above our train then right side of the train again in left side. I came out to the door of the train to watch it clearly I saw it clearly, generally a plane took at least 15-20 seconds or more to cross the area which it crosses in a blink of an eye,and the lights were really unusual. It happens after we cross the station CHETAR somewhere in jharkhand I think and stopped where few days ago a train accident happened lots of flud lights are there the train also slowed down there. I you want I can give you all the details. Kindly reply me. Thanks and RegardsSANDIP ROY +918013169556
