Hi all,

I ask to those who are more experienced
than me,clarification about Sikhote Alin's
splinters formation.
In my opinion there can be two ways to
justify the origin of the fragments found in
the vicinity of the largest craters,
1) The kinetic energy released at the contact
surfaces of meteorite/ground was enough to
melt the frontlayer of the meteorite with
the subsequent violent expulsion of fragments,
fused or partially fused.
2) Having the meteorites reached the retardation
point at only 5 km of altitude, they would arrived
at an impact with their hot surfaces, this would
facilitate the expulsion of splinters.
I apologize for my bad English.
