We live in a south indian city called trichy. when i and my son 10 years old went up to the terrace in our apartment for an evening walk on july 17, 2016 at around 6 pm in the evening , we saw 3 beams of light in the sky. they formed triangular shape and were moving around in the same place after which a bat started circling above our head in a strange way. since it was strange so we came down to our home quickly
