Wanted to make a reply to a post on another thread about this, but it has expired, so I will post here:

Half of the birds bumped into something invisible in the sky and fell...

The passerby besides me also saw it and puzzled...

The invisible thing is parked between the clementi fire station and mrt station

You serious? This sounds like a scene from the movie "Signs", where a flock of birds collided into the UFOs that had somehow made themselves invisible.
And I was watching the clip of the Channel U news bulletin on YouTube ( http://youtube.com/watch?v=WcNq-oKjxWg ), and it said the thing flew from the east to the west. Clementi is in the west, so...

(edit: oops, I made a mistake here

)
Edit: OK, guys, I'm trying to plot the trajectory of the object on a Singaporean map by marking out rough locations where the object was spotted, and I
very seriously suspect that there was more than one object. Can anybody try to help me by posting the location where you spotted the object? The more specific, the better. Also, try to approximate the angle of the object in the sky relative to you, in which direction did you see it coming from, and how far it was away from your location. Also, did you see it from ground level? Or did you spot it from a high-rise building/near the peak of a hill?
I'm specifically looking for sightings reported from Changi, Paya Lebear, the North-East towns (Hougang, Sengkang, and Punggol), Tampines, Queenstown, Yishun, and Pulau Ubin/Tekong.
