i saw it in bright daylight, and i cant figure out what artificial aircraft is so ...........I was at my hostel where i chat with my fren thru the windows from 5th to 6th floor, suddenly i saw a black plate which is hovering like an eagle above us, estimated 100 meters from ground, when i find out that the aircraft is hovwering as slow as a helicopter but it is a plate-shape object, i quickly notify my fren above which is looking down at me, he look at it and ask me whether i think of the same thing, we saw it slowly hover by high up in the air, estimated as large as a car, we can clearly see the black saucer slope to right then left all the way it travels until it finally dissapear when it flew too far away, i noticed that it has a red light flashing at the back of it and i sort of see some bright lights surrounding the craft, i beleive it is shimmering, but since it is still bright outside, i couldn't be quite sure.
