Luke Aikins has made nearly 20,000 parachute jumps -- but this one was like no other. The sky diver, who worked on the film "Iron Man 3," jumped from an airplane without a parachute or a wingsuit Saturday as part of TV special called "Heaven Sent."Aikins jumped out of a plane flying 25,000 feet over Simi Valley. After two minutes of freefall, he became the first sky diver to safely land in a net, according to the Associated Press.Aikins says he knew it sounded crazy, but after two years of training, he wanted people to see that with hard work sometimes the impossible becomes possible.
