It was a clear day and not a cloud in the sky i was in the backyard taking photos of aircrafts that pass by. i have a bridge camera with 65x optical zoom.I have just finished taking a shot on one and as i take the camera off my eye, i noticed this tiny white object (i cannot tell the shape of it whether it is round or square) moving so fast. seems that it was traveling in a straight line and i have taken about 20+ photos of it until i lost sight of it. i enlarge the photos more on my computer hoping that i’ll be able to identify it i just couldn’t. it’s something that i have never seen before.
