Scientists Analyze Meteor Fragments - Universe Today
Researchers from the University of Chicago are analyzing hundreds of meteorite fragments that struck Park Forest, Ill. in the evening of March 26, 2003. Witnesses in several states saw the tremendous fireball when it struck last year, and volunteers eventually collected 30 kg of fragments; some that crashed through the roofs of their houses. It's believed that the original meteor weighed 900 kg when it exploded in the sky. The heavier pieces fell nearly straight down, and the lighter pieces were carried downwind a bit to create a huge swath of fragments.
