Indianapolis 500: The 70s (2004)

Culled from the vast library of the Indianapolis Motor Speedway archives, this documentary tracks the impact that technological changes such as turbochargers, ground effects and wings had on open-wheel racing in the 1970s. In addition to revealing interviews, race recaps, complete box scores and driver bios, this program also features Tony Hulman's fascinating retrospective "For Whom the Flag Waves."
