These types of crashes have happened before in central Pa and others.
Many years ago, Hodnett into the infield at Lincoln.
Coldren in 2012 into the infield with some pieces hitting spectators at Port Royal.
Few years ago at Williams Grove, crash on the front straight and parts, including an axle, into the lower rows of seats behind the starters stand.The one that I fear the most happening, is a car getting over the chain link fence at Williams Grove and bouncing through the front straight pits.
For a lot of tracks, better fencing and posts at critical areas, would do wonders for the safety of their drivers, crews and fans and probably would not cost a ton of money to implement.
If you are thinking about the same accident as I, the drivers name was Ned Powers. The entire front axle landed several rows deep in the bleachers. Fortunately it was a night when the stands weren't full and I don't think it hit anyone. If that would have landed in a packed row of seats, someone else would own the speedway.
There was a video on YouTube but I'm too lazy to search for it.
