I was in my terrace. It was my usual time for a chat on the phone, with my friends over the week-end. I was about to finish my phone call and suddenly I noticed a light coming from north-west direction and go towards the south-east direction. I first thought it was a normal aeroplane, as it was a cloudy night. Then I realized that it started to go back and forth in the same direction. It was doing it with great speed and the time it took to pause and then start again between its two stops were super-quick. I am sure we do not have such an Aero-Dynamic technology here in India. For that matter, the whole world !It was doing the same thing constantly for almost 20 mins.Description: It was just a Flashlight like object behind the clouds. It barely came out of the clouds and when it did, I could not see it. It was totally blank. Again when there was a cloud I could see the flashlight. The amazing thing was, the friend with whom I was talking to over the phone also witnessed the same thing (80 Kms apart) !I came down to my house thinking that it might abduct me, if was real !I checked after 1 hr, but it was no where to be seen.
