State officials now investigating how people became trapped as you see
right here upside down on a roller coaster in Wisconsin.
The thrill seekers at the festival in Camden,
Wisconsin got more than they bargained for when
the fireball roller coaster stopped mid ride.
On Sunday afternoon, eight people were left hanging upside down for three hours.
Firefighters from three different cities were sent to help the passengers,
most of which were minors.
They were taken to the hospital for treatment.
