2011 IZOD IndyCar World Championship
The 2011 IZOD IndyCar World Championship was the final race of the 2011 IZOD IndyCar series schedule. The event took place at Las Vegas Motor Speedway in Clark County, Nevada on October 16, 2011. The race was stopped following a major accident triggered by drivers trying to avoid light contact between Wade Cunningham and James Hinchcliffe. 15 cars were involved in the wreck, which resulted in the death of two-time Indianapolis 500 winner and 2005 series champion Dan Wheldon. After a delay of over two hours, IndyCar decided to abandon the remaining 188 laps after word of Wheldon's death was relayed to the drivers, though the drivers did complete a five-lap salute in honor of Wheldon.
Science Olympiad
Many states also hold invitational tournaments. These competitions serve as "practice rounds" for qualifying tournaments, and are hosted by individual middle schools, high schools and/or colleges. Invitationals occur most commonly in January or February, although there have been some as early as October or as late as April. Teams can participate in invitationals from multiple states depending on availability. At some invitationals, only a few events are held. However, many invitational tournaments mimic regional and state competitions in their competitive intensity. For example, MIT hosts an invitational tournament each year with around 70 teams from over a dozen states, including 20 or more past national qualifiers. Other tournaments, especially in the midwest, are well known for their quality and competitiveness. In this way, teams can gain extra practice before competing in regional, state, or national tournaments. In 2014, Yale University became one of the first institutions of higher education to host a tournament run by Science Olympiad alumni, with several more following over the next few years.
