I find it fascinating as well.

I am also amused by the enthusiastic tone of the article.

The last documented comet event occurred in 1908 in Russia near Tunguska in a deserted region of Siberia. Fortunately for us carbon life forms, it was small and it exploded about 10 miles above the earth instead of impacting it.

Seems it knocked down everything standing for a 15 mile radius and created a earth quake of 5 on the richter scale.
