Earth's gravitaional pull the pieces would be at the same place as the sattelites were, and wont get sucked in. So it probably came from a plane.
Wrong, wrong and wrong again. There is absolutely gravity in space, however objects in orbit travel so fast there is no realitive drop towards to the
center. Sattelites in low earth orbits regularly re-enter due to the repeated small tug of the very upper atmosphere. Other things such as 3rd body
effects, particle clouds, etc. could also push a sattelie (or piece of one) close enough to the atmosphere to re-enter.
And most metals used in space are resistant to heat and oxidation, so even after being heated during re-entry they won't neccisarly be a chunk of
charcoal...
