The Man Who Walked Between the Towers by Maria Slavin

I can't believe someone actually could walk on a wire 5/8 of an inch thick. I have a hard time one a balance beam which is 5.1 inches thick!

I wonder how long it takes to train to be a hire wire walker?

Another name for high wire walker is tightrope walker. They actually walk on a 1/2 in wire. Acrobats train for years and use mechanics (circus term for the safety wire attached to a performer executing a difficult or dangerous trick or feat) to safely develop routines.
