Acrobat loses footing and falls '30-feet' to the floor in front of screaming families

Families were left horrified after witnessing an acrobat fall to the floor when her foot "slipped" from a swing during a show at Winter Wonderland, MailOnline reports.

The ordeal occurred at the Zippos Christmas Circus Show at 6 pm during a performance of Cirque Beserk in London's Hyde Park. Staff rushed to Jackie Armstrong's aid when she began "yelping in agony", with the audience members being ushered out shortly after.

"The lady had one foot in the loop with no actual harness and her foot slipped out and she fell to the floor diagonally," a witness told MailOnline.

Children on the front row watched up close as the 35-year-old mother-of-one fell.

"Kids were on the front row and there were people screaming. She was yelping in agony, it was traumatic as she bounced as she hit the floor. There was an announcement after a minute or two to all leave," the witness continued.

The Kent native was rushed to hospital although her current condition is not yet known.

Another witness told The Sun Online:

"It was horrific. I thought it was part of the act but when she didn't get back up I knew something was wrong. A group of people ran on to help her and people were shouting for a paramedic. I thought I heard her scream or wail, so hopefully, she is conscious. But it looked terrible. People in the audience were coming out crying. There were quite a lot of kids as well."

Armstrong graduated from Christchurch University in Canterbury with a degree in theatre studies before she joined Zippos as an aerialist. She is engaged to 33-year-old Valter Jonas, a motorcycle stunt rider, who she met in 2011 when he joined Zippos.

Per MailOnline, a spokesman for Zippos Circus said:

"The female British artist, Jackie Armstrong, performs an aerial act and is a highly experienced circus artist with 10 years in the ring. Jackie was immediately attended to on the scene by first aiders and an ambulance called. She was taken to hospital by ambulance and further information on the nature of her injuries is awaited."
