I've seen a UFO (Unidentified Flying Object) today and I am sure it was some alien spacecraft moving very high in the sky. Basic details of this event are : Location : New Delhi (India). Date : 27th April 2014 Time of visibility : 07:57 PM - 07:58 PM Evening (Just for a minute). Coordinates of my exact location Latitude : 28.6236 Longitude : 77.2903 The UFO was moving at a very high speed. It was so distant that it looks like a star. Its direction was right over my head (90 degree straight upwards.) It was moving from South to North. I am pretty sure it was a ufo..why ? I am explaining some reasons : Why it can't be an Airplane ? : Forget it.. An ordinary airplane can't fly at so much higher altitude. It was a very distant object. Airplanes use to flash and flick the lights but it doesn't flashing. It was looking just like a star due to its higher distance. Airplane are slower even at low altitudes but that object was very fast at a extremely higher altitude. Its shape was also doesn't resembling any type of Airplane. Why it can't be a meteor or comet ? : Usually a meteor or comet leaves a long trial behind them but this object doesn't have any.They are also very bright but the object I've seen was not so bright like a meteor.There speed is extremely high so they can be seen only for a short interval of time (for few seconds). But it was visible for a full minute. The object takes just a minute to travel a massive distance from South to North. It was very fast but not as much extremely fast as a meteor or comet..but believe me it was very fast... After doing some more investigation on it.. the last possibility i found was it may be a satellite, ISS of NASA. Then I navigated to the official NASA website and checked that weather there are some visible satellite activities happening over my location or not. I set my country and city. NASA thrown a list of events and I was pretty much surprised by results because there is an event of visible satellite today in my city. Then I was pretty sure that it must be NASA's ISS sighting .But then i found some more shocking and interesting results.The details of that event are as follows : Date of possible ISS sighting : 27th April (Same) Now the shocking details.. Time of visibility : 07:20 PM (About Half an hour earlier) Total visibility time : 06 min (The object I've seen was visible only for a minute). Appears : 16 above North North West Disappears : 10 above East South East (mine was South to North) Maximum height : 52 degrees (mine was at straight 90 degrees) After comparing these details... its confirmed that it was not any ISS of NASA because the details provided by NASA and my reported details are differs so much. Time was half an hour earlier, visibility duration was one minute,directions are too much different and height also.
