The racing world is mourning the loss of two-time Indianapolis 500 winner Dan Wheldon, who was killed in a horrific 15-car pile-up Sunday, during a race in Las Vegas.
Starting in the back of the field, Wheldon was moving his vehicle through the pack when several cars began getting tangled in front of him.
Unable to avoid the wrecks, Wheldon's car clipped one vehicle and flew over another on lap 11. His car burst into flames as it flew into a catch fence.
He was air-lifted to University Medical Center, where he later died. The husband and father of two was 33-years-old.
Wheldon's death was announced by IndyCar CEO Randy Bernard.
"IndyCar is very sad to announce that Dan Wheldon has passed away from unsurvivable injuries," he said.
"Our thoughts and prayers are with his family today. IndyCar, its drivers and owners, have decided to end the race," he said.
In his honor, drivers, many sobbing openly, took part in a five-lap salute around the 1.5-mile oval as thousands of fans stood and cheered from the grandstand.
Also injured in the crash were JR Hildebrand and Pippa Mann. Both remained in the hospital overnight.
IndyCar said Mann was being treated for a burn to her right pinkie finger and will be released Monday morning. Hildebrand was awake and alert but will be held overnight for further evaluation.
An autopsy was planned Monday for Wheldon.
Many of the drivers called it the worst crash that they have ever seen during their racing careers.
"I'll tell you, I've never seen anything like it," Australian driver Ryan Briscoe said. "The debris we all had to drive through the lap later, it looked like a war scene from Terminator or something."
"I mean, there were just pieces of metal and car on fire in the middle of the track with no car attached to it and just debris everywhere," he said.
"So it was scary, and your first thoughts are hoping that no one is hurt because there's just stuff everywhere. Crazy," he added.
IndyCar has not had a fatality since Paul Dana was killed at Homestead in 2006 during a crash in a morning warmup.
