Hi Bruce, Phil, and list,

It has always been my understanding that the debris from a major impact
would plume into the upper atmosphere.  My gut feeling is that the rising
vapor from any boiling oceans, while possibly rising higher than normal rain
formation, would not make it up as high as the existing, spreading, dust
blanket.  Therefore, the dust could not be 'rained out' as it would exist at
a higher level than any recycling effects water vapor might have.

Best Regards,
Julia
