SANTA CLARITA, Calif. (AP) - The state agency that investigates workplace accidents says it was an entire tree - not just a branch - that fell onto a roller coaster's tracks in California, dislodging the front car and keeping nearly two dozen riders hanging for hours.
Peter Melton, a spokesman for the Division of Occupational Safety and Health, said Tuesday that the Ninja coaster at Six Flags Magic Mountain will remain closed until investigators determine exactly what went wrong.
It took nearly three hours for all 22 of the stranded riders to be rescued Monday night. Four people suffered minor injuries.
At least one of the cars, which are normally suspended beneath the track, was derailed.
The park's website advertises that Ninja swoops through the trees at up to 55 mph.
