39 people had to be rescued from a ride at the Chessington World of Adventures theme park, after it got stuck in the air.
Most of the people on the ride were children and were stuck on the Rameses Revenge ride for more than three hours.
Fire crews had to remove safety harnesses and brought everyone to the ground on ladders.
They said no one was injured but a few people were uncomfortable after being stuck for so long.
Chessington World of Adventures, which is in South West London, has apologised saying: "Initial attempts to bring the ride down were not successful and the Fire Brigade was called to assist and arrived on the park within seven minutes.
"We are very pleased to report that the evacuation was completed by 7.30pm and that no one was hurt during the incident.
"The ride will remain closed while investigations take place into the cause of the stoppage and any required remedial work is completed."
The Rameses Revenge ride has two rows of people and turns you upside down, lowering you head first over water fountains.
