Felix Baumgartner takes Anderson Cooper through the experience of breaking the sound barrier during his historic jump. "Until I opened my parachute I did not know if I broke the speed of sound or not. So when I touched the ground with my parachute, I have been told by a lot of people on the ground they heard the super sonic boom. It's the first and only super sonic boom created by a human," said Baumgartner. The skydiver said he was worried about nailing the perfect landing without falling because "the whole world was watching."
