The Flying Wallendas Through the Years

22 of 23: High-wire acrobats Delilah Wallenda, right, lowers her head as her son Nik Wallenda, left, crosses over her during their high-wire act where the two simultaneously walked across a 300-foot-long wire suspended 100 feet in the air between two towers of the Conrad Condado Plaza Hotel in San Juan, Puerto Rico, Saturday June 4, 2011. Nik's great-grandfather, the German-born Karl Wallenda, tried to perform the same feat in 1978 but fell to his death at age 73. The two Wallendas commemorated the famous family patriarch by successfully completing the same stunt Saturday. He was the founder of the "The Flying Wallendas" high-wire act.
