I love a challenge, and trying to become the first person to break the speed of sound in freefall is a challenge like no other.

That spin became so violent, it was hard to know how to get out of it. I was able to get it under control and break the speed of sound...I could feel myself break the speed of sound. I could feel the air building up and then I hit it.

If I do something, it's always 90% obvious and 10% unknown.

One of the most exciting moments was standing out on top of the world, 30 seconds before stepping off.

I like to challenge myself.

To jump and break the sound barrier will not be a mere record breaking experience or another extreme event that ends once the mission is accomplished.

I base jumped off the Jesus statue in Rio de Janeiro.
