How Does Sean Casey's Tornado Chaser Work?

Sean Casey's Tornado Chaser — a reinforced Ford F-450 diesel dually — is just a tool, like his IMAX camera, with which he's planning to record a direct hit by a catastrophic twister on film. It'll be the ultimate atmospheric money shot, and Casey needs the truck to fulfill two basic needs on the mission: transportation and shelter, not only from the high winds, but also from the deconstruction materials, vehicles and cows swirling around inside the average cyclone. How Stuff Works takes a look at what went into building such a reinforced basement on wheels, and what might keep it from becoming a projectile before the deed is done.
