Hi Pete and List,

In other words, the impacting meteoroid would have had to have a mass
big enough to reach the ground at cosmic velocity - impossible for small
pieces like the Tamedaght stones! This would take an iron like the Hoba
to survive such deceleration forces. But even the Hoba iron seems to have
landed rather "smoothly". So something like the Canyon Diablo impactor
is necessary to yield the results described by Aziz Habibi.

My two Euro-cents,

Bernd
