French firefighters say three adults and five teenagers were trapped high in the air on a broken fairground ride for more than eight hours from New Year's Eve into the early hours of 2019.
The revelers - the youngest aged 13 - were stuck about 52 meters (170 feet) above the ground in the city of Rennes, in western France.
Witnesses quoted by local newspaper Ouest-France said the pendulum ride broke down around 8.30 pm Monday amid noise and sparks, leaving one of the two passenger sections suspended at the highest point.
Firefighters used a helicopter to reach the trapped people and provide them with harnesses so that they could be winched down onto a firefighter's ladder.
They all safely reached the ground by Tuesday morning.
