In this case, no trajectory for the Russian bolide was needed to come to that 
conclusion.

With a geocentric radiant at declination -81 degrees for the 2012 DA14 orbit, it 
is impossible for fragments from an associated "stream" to impact at a latitude 
as high as 55 North. As seen from the viewpoint of approaching 2012 DA14 
fragments, 55 N is the "backside" of the Earth.
