One of my friends owns a book previously mentioned on Da List, Rain of Iron
and Ice. In it, a number of scenarios are extrapolated for asteroid impact,
ranging from little effect to widespread devastation, depending on a number
of factors. I suggest you take a look at this book, if you can get your
hands on it -- a good and informative read.

>Woud the same principles be present in a large asteroid disintigtating
>(exploding/vaporising) just before it impacted on earth within our
>atmosphere, should it make it in that close ( Tugunsta and
>similiar)? In that, the pieces, metal bearing ( heat condusive), would
>be subject to our gravitational and friction factor, depending on what
>velocity and distance, they are spewn apart to ? Friction is a factor in
>our atmosphere, once it explodes here, frozen or not, isn' it ? How much
>heat, due to our friction, if any, does a shockwave accumulate? I know
>there is no way of measuring an exact answer for this question, as every
>occurance and strewnfield is different, but
>I really don't understand why, under these circumstances, a margin of
>credability doesn't exist? The provrbial, exception to the rule? Could
>it be that the shockwave, not the meteorite fragments, itself could
>create under the right climate ( hot dry) the ability to generate enough
>heat to ignite combustible earth matter?
>Excuse my ignorance, but I would sincerely, as a student, like any
>possible answers or theories to my querry, from anyone that would be so
>kind. Best Regards, Marcie
