   I have read in other newsgroups of the concept of a "relativistic kill   
   vehicle" that might be used in future space-based warfare. Disregarding   
   whether or not the concept might make any military sense, has anyone   
   calculated the effect of (say) a 1kg mass hitting the Earth's atmosphere at   
   0.9c, which would release about as much energy as a 1kg antimatter   
   explosion?   
      
   Would the explosion occur in the upper atmosphere, or could the projectile   
   make it to the ground before it was fully vaporized?
