A seven-year-old boy was among 24 people who had to be rescued when a popular ride stopped mid-air at Hull Fair on Saturday night.
City Star Flyer broke down suddenly leaving horrified thrill seekers suspended in the air on seated swings.
One rider – a seven-year-old boy – was given medical treatment at the scene.
Staff were force to scramble up the ride to assist people who were trapped for around 30 minutes, according to a witness.
They told Hull Live: “Two workers going up the rescue. Still up there no sign of the fire brigade either.
“They’ve been up there for some time now.”
Two people who were on the ride when it broke down said they were left shaken and nervous.
They said felt as though the ride was going to drop and grew cold as they were suspended high in the air.
Zara Tomlinson, 21, from west Hull, said: “We were on the ride for ages. We had no idea what was happening. I thought the ride was just going to drop.”
Miss Tomlinson also explained how she “almost blacked out” on another ride, which made her “even more nervous.”
Another passenger, James Goodwin, 22, from west Hull, said: “We were a bit nervous and we were a bit shaky when we came down. It’s cold up there and we were getting very chilly.”
A worried relative who stood waiting for their two teenage family members to be rescued from the ride said at the time: “We are quite worried for them, we don’t know how long they are going to be up there for and we just hope they’re ok.”
The City Star Flyer is now back up and running.
The Hull Fair is one of the largest travelling fairs in Europe, that features over 250 rides and an array of attractions.
