were bigger than the biggest US bombs), strap them together into a cluster, 
and
then place duplicate copies of those clusters every 4.5 to 5 miles apart, all
over the surface of the earth and oceans, you would roughly match the average.
Thank goodness, the actual energy distribution was uneven, because I don't 
think
anything much would have survived a uniform distribution of that magnitude,
which would be equivalent to having 28 of these individual bombs go off within
2.5 miles of you, no matter where on the planet you were located. >> 

       Sounds like some hangovers I used to get in the "good" old days. 
       To me these seemingly endless K/T extinction discussions quickly get 
tedious beyond words. Luckily, Jim Cunningham always finds a way to scare you 
and I then have another oppurtunity to plug Doug Henderson's latest book, 
_Asteroid Impact_, a little book with some of the finest 
paleontological/astronomical illustrations ever made. Buy it. DV
