Fans Injured At Nascar Race in Daytona

Two weekends ago in Orlando Florida at the Daytona International Speedway there was a big wreck during the Nationwide race causing a racecar to get lifted into the fence protecting the fans from getting hit by any debris, but the fence couldn't stop what was comming through it this time.  On the very last lap of the race the number 32 car lost control and was lifted into the air almost like a rag doll.  There was over 20 people injured leaving 2 in critical condition. The driver of the car had no injuries.  I happened to be watching the race on those very last laps and it was a very intense moment. There was absolutly nothing left from the front of the windshield to the bumper. The motor was even left right by the front row of seats. If i had been at this race I would have felt bad for the people sent to the hospital. Have any of you seen or heard about this? If so, please comment.
