For the second time in less than 18 months, NASCAR and track officials in Daytona Beach are taking a close look at safety systems following a horrific crash.

The latest incident happened in the early morning hours Monday during the rain-delayed Coke Zero 400.

Austin Dillon's car went airborne, into the fencing at the end of the race, sending debris into the stands.

While Dillon walked away from the crash, 13 fans were hurt with one sent to an area hospital.

That person was treated and released.

Daytona International Speedway officials would not allow us access inside the track Monday to get a better view of the catch fence and damaged caused by the last-lap crash.

However, video shot from the air shows there is a lot of work to be done to fix the section of track fencing Dillon hit.

In a statement, the 25-year old driver said “it was a wicked ride...” and that he hopes “everybody in the stands is all right.”

After a long weekend at the track, long-time race fans have seen this play out before at this track.

Mike Hartsock from Hobe Sound remembers one in particular.

“I was here when Geoffrey Bodine went into the fence in the actual first truck race and back then we didn't have the actual fence like we have now. I was so glad to see that there was nobody really seriously hurt and Austin Dillon walked away,” he said.

Hartsock said Dale Earnhardt's death at this track was the biggest wake-up call for the sport. Earnhardt's son, Dale, Jr. won the Coke Zero 400 last night.

He saw everything happen in his rearview mirror and said while the cars do have safety featured designed to slow them down...

“There are rare occurrences where, you know, it's an oddity how those cars collide tonight that Dillon didn't get that chance for his car to slow down.”

As for what's next, track president Joie Chitwood, III points to the ongoing $400 million overhaul called Daytona Rising, which includes new safety measures.

“One of the elements of Daytona Rising was no longer having fans or individuals on rim road and then closing off the grandstands on the front row. So those were in the new sections and that's what was in place today and I think did a very good job.”

Chitwood also says track engineers will team up with NASCAR to take a closer look at the wreck and how the safety measures worked as well as what needs to be improved.

There's no word if that will impact the work that continues with Daytona Rising, slated to wrap up in January before the Daytona 500.
