Mack Trucks employees built it and a Mack truck recently delivered the Space Shuttle Blake, a mobile classroom, to the Kennedy Space Center in Florida. The Blake has been on its mission of educating students about space exploration for over 20 years now. It was the brainchild of Bob Boehmer, a teacher at Schnecksville Elementary just outside of Allentown, PA, who came to Mack in the early '80s with an old military transport bus and the vision of transforming it into a classroom-on-wheels for space-related education. Mack employees were asked by Boehmer just to paint the bus, instead they went whole dog and turned it into a drivable model of the space shuttle itself.
