Two storm chasers shot some pretty amazing footage from INSIDE a tornado this week.

Brandon Ivey, Sean Casey, and Herb Stein intercept a violent tornado in Smith County, Kansas on May 27th, 2013.

The twister touched down on Monday, and they were in basically a half-car halftank called a "Tornado Intercept Vehicle."
It's not clear how big the tornado was, but they say the winds were blowing between 150 and 175 miles an hour.
