(CNN) Parents and players watched helplessly as a strong gust of wind blows an inflatable slide across a field and into the middle of a Colorado lacrosse tournament.

“We thought the girls were going to get taken out cause this thing’s massive.” Recalls a witness to the horrifying scene, “As the wind picked up, it would tumble. Like a bag in the wind.”

“All of a sudden, it picks up and there’s a girl going down the slide. She flies out about eight feet in the air.”

A 10-year-old girl was thrown from the bounce house right away, but an 11-year-old boy continued to tumble another 200 to 300 feet before the slide finally came to a stop. Both are recovering from minor injuries.

Airbound, the company operating the bouncy slide, says they maintained all safety precautions including having their staffing onsite.

They gave a statement saying:

“We did have the inflatable properly staked to the ground. We do wish that we had been able to foresee the microburst wind and shut the ride down prior to this incident occurring.” ** and that in no way, shape or form were we trying to operate that ride in those winds.”

This isn’t the first time these party favorites have gone airborne. Just last month three children playing inside a bouncy house in New york were sent flying nearly two stories when the inflatable structure was blown off the front yard.
