THIS is the moment children were left screaming in terror when a funfair ride lost power in mid-air.

Astonishing mobile phone footage shows the lights suddenly go out on the No Limit giant swing.

Panicked screams then ring out around the Funderworld pop-up amusement park in Clifton, Bristol.

Kate Duncalf, from Liverpool, looked on in horror as her daughter was one of just two people on the attraction at the time.

She told how they were left swinging in darkness following what is believed to be a generator failure at about 7pm last night.

The mum said that despite power returning within a minute - it took as long as 20 minutes to bring the ride under control, because of the momentum.

She told The Bristol Post: “My daughter had a panic attack while it was still swinging. I’m going to take her to the doctor to make sure she’s ok. She’s in bed shaking from utter shock.

“As far as we were concerned those kids were going to fall off and die in front of our eyes.”

The attraction is essentially a giant swing with those who ride it sent swinging 360 degrees through the air.

On Funderworld’s website it is described as: “Seating 16 Passengers, and reaching a height of 24 metres, passengers can experience up to 4.5gs.

“Looping in random projectories [sic] all the time, experience both negative and positive forces.”

A Funderworld spokesperson said: “There was a short power failure last night at Durdham Downs, Bristol which lasted for around 20 seconds, it affected 6 of the 50 Rides & Attractions on site. All of the safety features on the rides affected automatically went into place, which insured that the safety of the occupants was not compromised at any time.

“All Fairground rides carry ADIPS certification which insures that the security and safety features of all rides meet the required safety standards.

“An expert specialist is visiting the site this morning to diagnose / rectify any issue there may have been with the generator. Should the need arise our on site backup generators will be commissioned.

“Funderworld be will be fully operational on the Durdham Downs this evening and daily until April 8.”
