The fiery crash at NASCAR that left 28 injured has many wondering whether some spectator sports are safe.
The smashup sent pieces of debris flying into the stands. A video was shot by a 16-year-old spectator.
The teenager called in to ESPN and said, "I remember hearing screams and I heard one fan yell, 'where's my child?' and that's what really hit me really hard."
A tire went flying into the crowd, badly injuring a spectator.
It's the latest proof that danger can lurk in an instant at big outdoor events.
Ten people died when a stunt plane crashed into the stands at an air show in Reno. During an off-road race in the Mojave Desert, a truck plowed into the crowd. The awful aftermath was visible after the crash, the car upside down and spectators pinned underneath. Eight people died in the horrific 2010 accident. A speedboat roared out of a lake in Ohio and injured 23 people. A woman was killed when a souped-up car crashed through the safety barrier at a racetrack in Virginia.
Even the so-called sport of kings can on rare occasions be perilous. A racehorse went wild and trampled a stroller. Miraculously the baby in it was not hurt.
Now, this latest pileup has many people thinking twice before they head into the stands.
