diana set out to do the most outrageously difficult swim she could imagine. cuba to florida. over 100 miles in vicious currents. 200,000 strokes, 60 hours. she had a shark cage built, headed to cuba, and launched from a beach surrounded by press, despite grave concerns. >> and i remember, i got down to the shore with my six handlers, and i have a picture of the six of us looking bewildered. we're looking out at a raging sea of white caps. >> her navigator promised calmer seas just offshore, but instead, diana battled eight-foot swells for almost 42 hours. hopelessly off-course and ravaged by jelly fish bites, her handlers eventually pulled diana from the water. >> i didn't stop kicking for 42 hours. it was really rough. you can ask anybody. >> diana's dream was dashed and her heart was broken.
