Two toddlers were hurt when an inflatable bounce house they were in was lifted by a gust of wind and blown about 40 feet at a Nashua, New Hampshire, farm.

Authorities say a 2-year-old boy and a 3-year-old boy had climbed into the bounce house at Sullivan Farm on Sunday when it suddenly went airborne, flying over a fence and then crashing to the ground. The younger boy suffered critical injuries and was flown to a Boston hospital. The 3-year-old boy also was injured.

The farm's co-owner, Gary Bergeron, told WMUR-TV (http://bit.ly/1w1HPKs) that the bounce house had been inflated so it could dry off and was not open at the time. But the father of one of the injured boys says a farm volunteer led visitors to believe it was open.
