I believe they are saying these are from the satellite crash.
That's what I was thinking too. Low earth orbit is littered with all kinds of debris. The Russians had two spy satellites crash into each other a few days ago. Any time they want to look at a hot spot some place in the world they start popping a bunch of satellites into low earth orbit.
You know what the odd thing is? I've seen a fireball travel slowly across the sky in Singapore many years ago. It was "flying" quite low, so I had a good view of it. Weird thing is, no one else that I asked saw it, and no air disasters happened around that same time either.
