Italians in the 90's said mineral evidence in the area suggested a 
meteor/asteroid origin.  Russian teams, one using Ground Penetrating Radar in 
2010 and another using mathematical modeling in 2008 say "nope, it was for sure 
a comet".  Kelly 2009 said the "sky glow" effect suggest comets as well.  Does 
the US astronomical community have a particular take on the current body of 
evidence, one way or the other?
