As you have mentioned in the characteristics an aircraft was around the event & that object had lights emitting around it.Hi Sirs, This is not a joke or a hoax. I really don't believe much in these UFO's or aliens. But today i was very much astonished with this event. Today i was leaving to office (Am working @ night shifts) then suddenly i heard an aircraft flying. Just as normally i watched the sky but i saw a rather amazing sight. A triangle shaped or might be something else was moving across the sky. Then i thought might be the cloud was moving past. But i watched it for next few seconds the one was followed by almost 30-40 similar things & they formed some kind of a Random formation.They moved very fast but they were like a swarm & moved along swiftly. Soon they went past my eye sight. I went to the terrace & some of my friends saw it too.Now i have no choice left to believe in these things & "We are not alone"
