An investigation has begun at Alton Towers theme park into why a ride broke down, leaving passengers stranded for three hours.
It said around 80 people were on the Sky Ride cable cars when one of them became jammed at about 1630 on Tuesday.
Nine people inside it had to be rescued by staff trained in abseiling techniques.
The other cars were working but the visitors had to wait while their fellow riders were freed.
Nobody was hurt in the incident.
Alton Towers said everyone who was stranded had been offered a refund or free tickets to come back to the park.
The Health and Safety Executive was informed but the theme park said the HSE has decided not to investigate the problem.
The investigation will be carried out by Alton Towers,
Fire crews were called to the Staffordshire attraction although they were not involved in the rescue.
