Those with a fear of heights, look away now.
The stunt siblings known as the Flying Wallendas have completed their latest feat – walking a tightrope suspended over Times Square in New York.
Nik Wallenda and his sister Lijana Wallenda carefully made their way between two skyscrapers, 25 storeys above the pavement.
It was Lijanas first time joining him since a near-fatal accident in 2017, when she broke nearly every bone in her face trying to break a Guinness world record with an eight-person pyramid.
The siblings walked from opposite ends of the 1,300-foot wire suspended between the towers on Sunday night, crossing each other in the middle, where Lijana sat on the wire and let her brother step over her.
Both then continued to the opposite side.
It was streamed live on ABC and watched by thousands of people below.
