The aerialist performed a series of maneuvers Thursday morning including hanging from her teeth, toes and knees all while on a hoop suspended from the helicopter.
Erendira was tethered to a hoop suspended from a helicopter.
The stunt was coordinated to commemorate the fifth anniversary of Nik's original 1800 foot crossing over the Falls.
Legislators and the Wallendas said the payoff would come later, with the spread of photos and video from the stunt.
The aerialist's performance broke a world record, previously held by her husband, Nik Wallenda.
During the approximately 20-minute flight she used her teeth to grip on to the mouth piece for 10 seconds on her first attempt and then again for five seconds.
Today's televised stunt, hyped by local authorities, is expected to last about seven minutes.
Officials declared June 16, 2017, Erendira Wallenda Day in Niagara County, New York.
She said as an artist and as a daredevil, there's something "almost magical" about the falls. "But as you get older, it's all about other people and inspiring".
"It gives me goose bumps", he said. In fact, the two met while watching their parents perform.
Nik and Erendira have been married for 17 years and have three children. His grandfather would ride a bicycle on a tightrope while his grandmother dangled from her teeth below it.
The daredevil couple insinuated they could perform a duo stunt together in a few years. "You could see she was making a few moves up there, definitely, changing positions, going horizontal, putting her legs out".
Erendira said she wanted to spend more time in the air, but there was no way to communicate that to her husband. In a press conference after Erendira's successful stunt, Nik confirmed that despite suffering injuries, the five performers are already training or performing again.
