Mega Disasters: 65 million years ago an asteroid crashed into Mexico's Yucatan peninsula. 75% of all life vanished, but could a single asteroid have been the lone killer? Theories about what happened after the impact have been speculated on by the scientific community. Ranging from global warming to worldwide firestorms, ideas have been put forth, but none have been proven. Then in 1995 a new theory claimed that a powerful storm known as a Hypercane caused the extinction. The Hypercane allegedly reaches 20 miles into the Stratosphere and has wind speeds of up to 700 miles per hour.
