Aerialist Nik Wallenda has made history becoming the first person to walk across Niagara Falls on a tightrope.  He did a bit of a victory sprint on the final portion of the hair-raising walk.  Wallenda was calm as he slowly, painstakingly, proceeded step-by-step on a steel cable stretched over the falls, he even found time to grant a quick media interview, calling the view unbelieveable.
He was greeted with loud cheers from the thousands on hand to watch him, and Canadian customs officers asked for his passport.
