In what sounds like a nightmare for anyone who is scared of heights, Erendira Wallenda hung from a helicopter by her teeth over Niagara Falls on Thursday.

Erendira, the wife of daredevil Nik Wallenda, performed a series of stunts Thursday morning while dangling on a hoop attached to a helicopter hundreds of feet above Niagara Falls. Wallenda was tethered by the waist to comply with a N.Y. state law that requires safety harnesses for performers more than 20 feet in the air.

Despite what seems like a gamble with death, Wallenda told reporters ahead of the stunt that she was "not going to be freaked out," The Buffalo News reported.

"You can't do what we do and be freaked out," she said. "If you're scared of it, then it becomes dangerous. I respect what I do, but I definitely will be taking in the view. That's a once-in-a-lifetime opportunity, but I'm definitely not fearful."

Erendira broke a record her husband set in 2011 by hanging from his teeth 250 feet in the air.

The stunt took place on the 5th anniversary of Erendira's husband walking across a tight rope suspended above Niagara Falls.
