We're hearing this morning about yet another accident involving a bounce house.

Two New Hampshire toddlers were injured, including one critically, when the bounce house they were playing in was swept away by wind. 

The accident occurred at a Halloween festival when the boys started playing in the structure before it was properly secured. 

"The ride wasn't open. The tickets weren't on sale yet. No one was supposed to have been in there," said the bounce house owner.

The three-year-old was released from the hospital, but the two-year-old victim remains in critical condition after being airlifted to a Boston hospital. 

Witnesses say the inflatable structure was blown about 30 feet high and sailed 50 or 60 feet away, landing in an orchard. 

It's at least the third serious bounce house accident to make headlines in recent months.
