Its around 8:50 pm when i came back from my tuition and decided to go on the open roof of the house to spend some time alone with some refreshing songs. and then just like 15 minutes later at 9:10 pm i saw some glowing orb like things are coming from the north in a straight formation and they are like glowing fire balls hovering in the sky. there were no clouds at that time so, i saw every thing clearly and they were going just like a programmed path created by some one. they just passed the sky above my head and i witnessed it like 40 seconds long and there were not a single sound of those aircraft's. they headed towards the south and suddenly boosted upwards and disappeared in the sky. and i had no phone that time cause i listen music in a jukebox so was not able to capture any of the aircraft's.
