How a misbehaving meteorite changed the rules
The Tech Herald: A fast-travelling meteorite which struck a region near the Peruvian/Bolivian border in September 2007, should according to standard theory, have disintegrated in the Earth's atmosphere long before reaching the ground.

The fact that the rock meteorite didn't perform as expected and instead crashed to earth leaving a deep 49-foot-wide (15 meter) crater, means scientists must now rethink their meteorite theories, said Peter Schultz, a professor of geological sciences at Brown University in Rhode Island.
