I have personally seen UFOs karon lang nga year, 3 occasions about 3 months ago. What I usually see is a very bright light appearing suddenly, not moving, and no blinking lights (which would indicate to be an aircraft) and then the light slowly fades away and disappears. I sometimes see the same moving slowly on a certain direction, just a straight path, suddenly appearing, very bright and slowly disappearing into the darkness. All this happens in less than 30 seconds.
