Would it be possible for someone with a prosthetic leg to do the Flight Line? I am most concerned with what the landing is like. Is there a lot of strenuous walking before the Flight Line? The person with the prosthesis is able to walk normally and most people wouldn't know that he has one.
My answer is 'no'. A person with a prosthetic leg would have problems with this excursion. You are going 40 mph over a 1/4 mile zip line that ends with hitting a set of braking buffers on the cable. It is very much like going from 40 to Zero in about 5 seconds.
