I was on my terrace watching the beautiful sky and at the moment I had a feeling of something like watching me and I looked on the sky then there was a chopper.The thing which made me observe the object was a light bright light at the sky.I thought that it was a star.After a moment I saw that the object was started moving at a very high speed and I never saw such a speed in my entire life and then when that sphere starts desending then I was shocked and taken cover behind walls.Unfortunately I forgotten my mobile and I cant click any pictures of that object.After exact 20 minutes the object ascends and lost in the clouds.
