Nik Wallenda has successfully crossed Niagara Falls on a highwire strung high above the raging waters, a historic achievement for the American aerialist.

Wallenda, who hails from a long line of high-wire artists — several of whom have died during performances — started from the U.S. side at around 10:15 p.m. ET and completed it about 25 minutes after he started.

During his crossing, Wallenda spoke to his father through a headset and even took questions from ABC broadcasters as he made his way across the specially installed cable, which was about 550 metres long and roughly five centimetres wide
