The 2015 ABC Supply 500 was an IndyCar Series event that was contested at Pocono Raceway in Long Pond, Pennsylvania.

Similar to the crashes of Josef Newgarden and Ed Carpenter earlier that year at Indianapolis, air got under Kimball's car and lifted it off the ground.

The car landed on top of the SAFER barrier, slid along the wall, and impacted a fence pole with the rear wing.

The cars entered turn one four-wide as Pagenaud and Power pulled to the inside of Castroneves while Josef Newgarden moved to the outside.

Leaving the pits, the left-rear wheel fell off the car of Jack Hawksworth and a caution was waved to retrieve it.

The caution rearranged the running order, with Newgarden retaining the lead while Justin Wilson moved to second and Carlos Munoz in third.

On lap 85, Jack Hawksworth made a late move to pass Charlie Kimball in turn one and both cars collided.

On lap 132, Tony Kanaan clipped the apron in turn two and spun out, impacting the inside wall and breaking the left-front suspension.

On the restart, Marco Andretti lost control entering turn two, spun, and hit the wall with the right side.

On lap 152, Ryan Hunter-Reay drafted past Sage Karam and Simon Pagenaud to take to lead on the frontstretch.

With 37 laps to go, the ninth caution of the day came out when a fox ran from the infield and crossed the race track at the end of the frontstretch before it jumped over the wall.

On the lap 167 restart, Sage Karam in fourth position failed to accelerate with the leaders and created a major traffic jam on the frontstretch.

A highly competitive race, Karam's pass of Sato broke the event record of 28 lead changes set in 1973.

Leigh Diffey called the race on television with Steve Matchett and Paul Tracy providing analysis.

Matchett – Diffey's colleague from NBCSN's coverage of Formula One – was substituting for Townsend Bell, whose commitments to his United SportsCar Championship team took him to Virginia International Raceway that day where he finished first in his classification at the Oak Tree Grand Prix.

On lap 180 of the event, Karam was leading when he lost control of his car in turn one and made contact with the wall.

The impact tore away most of the front end of Karam's car and he slid to a stop just past the exit to Turn 1.

When Wilson, running fourteenth, drove by the scene, Karam's nose cone struck him in the head and knocked him unconscious.

A medivac helicopter was called for and transported Wilson to Lehigh Valley Hospital–Cedar Crest in nearby Allentown.

At approximately 21:00 local time on August 24, 2015, a press conference at Indianapolis Motor Speedway announced that Wilson had died from his injuries at the age of 37.

In response to the crash, IndyCar mandated that all nose cones and rear wings must be tethered to the car on superspeedways beginning in 2016 to prevent flying debris.
