Some of those rescued visitors, had to be lowered onto boats in a lagoon beneath the "Bayside Skyride."
San Diego Police believe a powerful gust of wind tripped a circuit breaker that powers the cables which propel the attraction.
Park workers could not restart the ride.
Officials say 16 people were aboard the ride when it stopped around 6:30 p.m.
