An inflatable slide went airborne in Colorado over the weekend, blowing 200 to 300 feet across a field and injuring two children. The terrifying incident happened in the Denver area during the Rocky Mountain Lacrosse Jamboree, according to television station KUSA.

“All of a sudden, it picks up and there’s a girl going down the slide,” witness Vannessa Atencio told KUSA. “She flies about eight feet in the air. The slide tumbles across the field.”

The girl was injured but treated at the scene, West Metro Fire Protection District officials told KUSA.

A boy appeared to be trapped in the slide and was carried hundreds of feet across the field until the bouncy house stopped, just before going into the water. The boy was taken by ambulance to receive medical treatment, but his injuries were not serious, West Metro Fire officials said, according to KUSA.

The bounce house was operated by a company called Airbound, KUSA reported.

A representative from Airbound did not want to comment except to say the slide was staked down into the ground and safety precautions were taken. But, weather stations in the area did record wind gusts of close to 30 miles per hour at the time of the incident at 2:40 p.m., according to 9News Meteorologist Marty Coniglio.

Police said two young boys, ages 5 and 6, who fell from the inflatable structure when it was 15 feet high remain hospitalized in stable condition - with one in a medically induced coma with a head injury, and the other with two broken arms and several broken facial bones. A girl, 10, fell out immediately and suffered minor scrapes.

In a similar incident last month, a Little Tikesbounce house flew up to 20 feet into the air in South Glens Falls, N.Y., seriously injuring two young boys.

One of the boys landed on a parked car, and the other on a street, parents told WNYT.

Local police told the television station that the toy was staked to the ground with spikes — just like the Colorado bounce house.

But in both accidents, winds were able to lift them anyway. In New York, winds of 24 mph were reported in the area, according to WNYT.

Bounce house-related incidents accelerated between 2005 and 2010, according to a recent study conducted by Nationwide Children’s Hospital pediatrician Gary Smith.

Every day, more than 30 children go to the emergency room with bounce house-related injuries, according to the Child Injury Prevention Alliance.
