 If I was going to write a book about my work life and I've actually given this a little bit of thought, it would be called heavier than air. I guess I would maybe call it something like on the move. I've traveled a lot for work and some of my work has been traveling. I guess I'd have to write the book first because I don't really have an answer, but I'm sure it'd be something related to aviation in the future of flight. The title would be work is rewarding. If you put some effort, if you put some work on, I'm sure you're going to get rewarded, maybe not right away, but eventually you will get rewarded. Well, if I was to write a book about my work life, I think that a suitable title would be a journey to modern hydrogen aviation.
