Like the main character in The Wizard of Oz, Dorothy will go into the heart of a storm. It's a heavily modified Ford E-350 van. Brennan Jontz and Dan Auel, who are members of Team Dorothy, built it.
They added sheets of steel to the van body and covered the exterior with Linex, a material that is literally bulletproof. Jontz and Auel hope that the skirts will prevent the wind from pushing the van over, as well as protect the tires from flying objects. The windows are half an inch thick and will hopefully protect the crew.
The team hasn't tested Dorothy yet, but they plan to the next time that a tornado rolls in.
