The big question is, which city or country is most deserving of a God-directed thumping by such a rock?

The major danger is more than just an impact. What happens if a relatively small meteor explodes during atmospheric entry at speeds above 33,000 mph at just the right altitude? Imagine a meteor exploding with the force of the W80 warhead from the AGM-86 ALCM cruise missile at maybe at most a mile off the ground--the shockwave from the circa 150 kT equivalent blast could could flatten wooden and brick buildings and severely damage steel-and-concrete structures.

looks like we missed it..

Interesting comparison:

Note that this one broke up “At an altitude of 5–10 km” and still had a pretty good wallop, including “Vegetation was incinerated up to 6 km from the impact site.”

So much for little ones not getting through to impact...
