Two dozen stuck on roller coaster in Calif.

SANTA CLARA, Calif. -- Rescue crews are using cherry pickers to remove two dozen people stranded between 40 and 80 feet off the ground on a roller coaster at a Northern California theme park.

Authorities say the riders on Great America Theme Park's Invertigo Roller Coaster in Santa Clara, Calif. are being lowered one at a time into buckets at the end of aerial ladders. All of the riders were expected to be back on the ground by 5:30 p.m. Monday, about 4 1/2 hours after the roller coaster came to a stop.

San Jose Fire Capt. Scott Kouns says the passengers are right side up and safely strapped into the ride. No injuries have been reported.

Authorities had first reported 32 people were stuck on the ride.

Authorities are blaming the incident on mechanical failure.
