Peter Jenniskens put a video on Youtube which was made by Jesse Carpenter and Greg Merkes of NASA Ames Research Center. The video shows the breaking up of the bus in much more detail. Notice how some of the fragments slow down so quickly once they separate: these are too light for the speed they travel and drag slows them down almost instantly. Also see how the capsule with hopefully the samples from Itokawa isn't bothered by the havoc that happends behind it and travels is a smooth trajectory. The flaring in the head of the bus is so bright that unofrtunate a bright blob obscures what is happening in the head. I hope that the LIME high frame rate imagery will be able to show more detail in that area.
