     A very interesting observation, being a perpendicular collision would that not lead one to deduce  that the fastest moving object was the Iridium, which lost it's kinetic energy to the Kosmos, thus spreading and increasing velocity of the kosmos debris, while losing momentum and spread on it's own?? 
    
    Just pondering it like a traffic accident in an intersection, ie. who was passing through and who ran the stop light and hit the other car... ;-)
