Check out this great video of the controlled destructive re-entry of the European Space Agency's Jules Verne Automated Transfer Vehicle.
The breakup itself began at an altitude of about 47 miles and produced some 600 fragments of 22-44 lb. in mass. The debris field covered a 125 x 1,250 mi. corridor about 1,250 mi. east of New Zealand and 1,675 mi. south of French Polynesia.
