Patrons at the Indy 500 line up to check out the Air Force interactive hangar prior to the race. The race day crowd saw 300,000 people come through the gates. The Air Force was making a strong push to those with interest in science, technology, engineering and math. The Air Force and Indy Car racing share many of the same traits in these rhelms.
