<<  Does anyone know where I can find any actual physical
 data regarding the compositions and/or heat transfer coefficients of
 meteorites?  How about information regarding the temperatures that meteors
 experience during their flight? >>

I didn't find those answers for you but, in Rocks from Space by O. Richard
Norton he mentions that as an iron hits the atmosphere it does heat up, but as
the lower temperature minerals reaches their melting point it just ablates
away leaving whats known as "thumbprints". Some meteorites are almost
completely eaten away. So ...could that be the way for the meteoroid to remain
"cool" inside? Also remember that when a large meteor reaches its 'retardation
point' and begins its free fall, it may be several thousand feet to several
miles of free fall also cooling the rock.
