I was reading an interview of Frank Zapata on The Verge about the Flyboard Air. I really like this quote about why they created it:
Honestly? I don’t know. [Laughs] You know when you decide to have a child, you decide to have a child because you want it. You don’t decide to have a child because it will become a surgeon, or a lawyer. For us it was the same thing, when we decide to create something, we create it, and after we just follow what ways the project can go.
