I assume that the pieces get enough time to decelerate to terminal velocity after its fragmentation and explosion in the upper atmosphere. If so, it would be like rocks falling from a great height - not supersonic, but you wouldn't want to get hit by one. One nitpick here - meteors aren't called meteorites until they hit the surface.
