Well, to me, my past accomplishments weren't crazy. They required a lot of skill and careful planning.

I was crossing the English Channel with a carbon-fiber wing on my back.

Aviation - and space travel, in particular - have always been especially captivating.

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.

Don't live life as a spectator.

I like to challenge myself.

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.
