Riders are left dangling 300 feet in the air for four hours when amusement park ride malfunctions.
Nearly two dozen riders were safely returned to the ground Wednesday night after having been stranded hundreds of feet in the air for more than three hours on a ride at California's Knotts Berry Farm.
The Knotts Berry Farm Wind Seeker stopped working around 4 p.m. when the ride's "safety security system activated," causing it to come to a halt, park officials said.
20 riders were stranded about 300 feet in the air near the top of the ride.
By 7:30 p.m., the ride had been manually lowered about half way to the ground.
At 7:40 p.m., the group -- which appeared to range in age from teenage to adult -- walked off the swings.
The Buena Park ride also became stuck on September 7th.
That time it took three hours for maintenance crews to manually lower the ride.
The ride has 32 two-person gondolas that go 301 feet in the air then swing riders for a minute at a 45-degree angle at eight rotations per minute, according to Knott's website.
No injuries were reported, officials said.
Knotts Berry Farm used its own maintenance crew to handle the malfunction.
