The 20-year-old shuttle, named Blake, is a quarter-scale replica of the NASA space shuttle Challenger, and uses an old bus as the frame. It's the creation of Mack Truck company and Parkland School District, which has a teacher with ties to NASA. The shuttle serves as a mobile classroom, teaching students around the country about all things NASA, with lab equipment, flight simulator and more, according to Mack.
The Blake was being hauled down the interstate by a Mack Pinnacle truck, which is being showcased by the American Trucking Associations' "Share the Road" highway safety program.
The shuttle will be used in a Memorial Day parade on Monday in Washington, said Eric Reler, a spokesman for the association.
