Indianapolis 500 winner Dan Wheldon died October 16, 2011 at Las Vegas Motor Speedway after his car became ensnarled in a fiery 15-car pileup, flew over another vehicle and landed in a catch fence just outside turn 2. The 33-year-old racer was a two-time Indy winner. In his honor, drivers took part in a five-lap salute around the oval.
