Question: The 2007 Firestone Indy 400 included a massive pile-up on lap 144 that ended the race for the four-time IndyCar champion of what nationality?
Context: George Dario Marino Franchitti, MBE (born 19 May 1973), known professionally as Dario Franchitti, is a retired Scottish racing driver.  He is a four time IndyCar Series champion (2007, 2009, 2010, 2011), a three-time winner of the Indianapolis 500 (2007, 2010, 2012) as well as a winner of the 24 Hours of Daytona (2008).  Franchitti started his career in his native United Kingdom in the early 1990s, competing in Formula Vauxhall and Formula Three and was also the winner of the McLaren Autosport BRDC Award in 1992.  After Franchitti did not secure a single-seater drive in 1995, he was contracted by the AMG team to compete in touring cars in the DTM and its successor — the International Touring Car Championship.  Despite 2 seasons with relative success, the series folded at the end of the 1996 season, again leaving Franchitti without a drive.  Mercedes placed Franchitti in CART in 1997 with the Hogan Racing team. The 2008 Firestone Indy 200 was the eleventh round of the 2008 IndyCar Series season.  It took place on July 12, 2008, at the Nashville Superspeedway.  It was the eighth and final running of the Firestone Indy 200. The Firestone Indy 400 was an IndyCar Series race held at Michigan International Speedway in Brooklyn, Michigan.  The event was most recently held in 2007.  From 1981 to 2001, the event was better-known as the Michigan 500, and was held in high prestige.  During its heyday of the 1980s, the race was part of Indy car racing's 500-mile "Triple Crown". The New Hampshire Indy 225 was an IndyCar race at the New Hampshire Motor Speedway in Loudon, New Hampshire.  It was held as a CART Champ Car event from 1992 until 1995, switching to the Indy Racing League for the 1996–97 season.  On June 21, 2010, it was announced that the IndyCar Series would return to New Hampshire for the 2011 season.  When the IndyCar Series returned to New Hampshire Motor Speedway the race was scheduled to be 225 laps.  A Firestone Indy Lights and NASCAR Whelen Modified Tour race accompanied the feature.  The race did not return for the 2012 IndyCar Series season. The 2009 Indy Racing League Firestone Indy Lights season began April 4 in St. Petersburg, Florida, where it ran a double-header weekend in support to the season-opening IndyCar Series event.  The schedule will take place over 14 race weekends in support of the IndyCars, with 15 total races.  Unlike the 2008 season, the St. Petersburg weekend will be the only double-header the series has announced.  J. R. Hildebrand ended the season as champion for Andretti Green-AFS Racing, winning the championship by nearly 100 points ahead of Vision Racing's James Davison and his AGR-AFS Racing team-mate Sebastian Saavedra. The 2007 Firestone Indy 400 was a race in the 2007 IRL IndyCar Series, held at Michigan International Speedway.  It was held over the weekend of August 3–5, 2007, as the thirteenth round of the seventeen-race calendar.  It was the last race, for the time being, for the IndyCar Series at the track.  The race was also notable in that only seven cars were running at the finish, after a massive accident on lap 144 of the race which included Dario Franchitti flipping upside-down after hitting Dan Wheldon.  Franchitti would walk away unharmed. Brendyn "Tyce" Carlson (born September 23, 1970, Indianapolis, Indiana), is a former driver in the Indy Racing League IndyCar Series.  He raced in the 1996–2002 seasons with 30 career starts, including 2 at the Indianapolis 500.  His 2 career IndyCar top ten finishes both came at the Las Vegas Motor Speedway in the 1999 and 2000 races.  He was forced to take several years off after repeated concussions but regained his health and from 2005 to 2007 sought a return to the Indy 500, however he failed to secure a ride.  He drove in the 2006 Freedom 100 Indy Pro Series event.  He now is a co-owner of a Firestone Indy Lights team (formerly the Indy Pro Series), Fan Force United. The 2007 Firestone Indy 200 was a race in the 2007 IRL IndyCar Series, held at Nashville Superspeedway.  It was originally to be held over 12 -July 14, 2007, as the eleventh round of the seventeen-race calendar.  However, persistent rain pushed the race back to July 15, 2007. The 2008 Indy Racing League Firestone Indy Lights Series season, formerly the Indy Pro Series, began on March 29, 2008 and consisted of 16 races.  Due to the discontinuation of the United States Grand Prix at the Indianapolis Motor Speedway, the series lost its Liberty Challenge double header typically held that weekend.  The Liberty double header were replaced by the addition of a second race at the Mid-Ohio Sports Car Course and a return to the Kansas Speedway, where the series has not raced since 2004.  All races were shown time-delayed on ESPN2.  Live stream video was available on the IndyCar Lights Series website.  It was announced on March 22, 2008 that Firestone signed on to be the title sponsor of the Indy Pro Series, and thus the series was retitled the Firestone Indy Lights, in reference to the old Indy Lights development series which ran under CART from 1986 to 2001. The 2009 Firestone Indy 300 was the final race of the 2009 IndyCar season.  This 297 mi race took place on October 10, at the 1.485 mi Homestead-Miami Speedway in Homestead, Florida near Miami.  The race was telecast by Versus.  Scotland's Dario Franchitti benefitted from late pit-stops for rivals Scott Dixon and Ryan Briscoe to take his second IndyCar Series title.
