hmm, I think they was cold becouse of falling down from higher layers of
atmosphere (dark flight) than becouse they still own a cold from space.
While this small specimens divide from a bolide they still got time to form
good crust so they must be hot or even little warm. Then they stop forming
crust and start this "dark flight" from a altitude of 20-30? km and there
are alvays extremely cold. If we add to this freeze wind factor we get very
cold meteorite.
Also if there was for example +30*C in Cali then even 0*C stone will be
"very cold" to person.
Im thinking correct ? Heh thats my imaginations at 4:00am
good night
